Dear Amplitude Team,


please prioritize multiplayer desync and "internet connection lost" issue.

As I have commented it has been apparently introed with the day 0 patch. Before that the game appeared absolutely stable.

it is actually ruining a fluid game play and consumes relevant amount of actual playtime just for loading the game over and over. 


please check the MP forum and the bug reports on this and merge. Please give us a message that you have received the reports and the estimated triage on this.

If there is anything missing for triage or fix please let us know.


I am aware there are dozends or critical issues just imho nothing like this is so disgusting.

Would be willing to rollback via Steam patch subscription to release build just to prove my point that the release was stable in this regard.

If you create a patch that needs opt-in (Total War games often do so) just to make more tests I would appreciate this much.


Humankind is an incredible game and it is just awesome to see what you have done in the time since the alpha and beta. 

I am aware you have very limited ressources and there are many things to look for and consider. 


Without MP this game would be another OFF the list for me and other people as nothing is more challenging or fun than playing vs or with other humans.

Fixing this would be a deed. A gift for Humankind.


Cheers,

al Qamar

its really a urgent matter since it costs too much time and nerves in multiplayer. Totally agreed.

@Lt_Miles thanks for taking care. It would be helpful to pin one of the threads or this to avoid further fragmentation.

@Lt_Miles @The-Cat-o-Nine-Tales can you confirm that this game has been tested without .net 3.5 on Windows 10? It was never needed before patch 1.

can you also confirm this game has been tested on Windows 10 with OneDrive KFM enabled for Documents?

Good job doing that but as i saw on the forum 8% of the community play multiplayer so its not critical for them to fix this and of course 8% is because people wont play a game with constant disconnect... snake eating his tail again that will need time all we can do is wait and hope or refund if its not too late.

Something that caused desync without fail in a game I played with friends is when someone pressed end turn and then proceeded to order units around, start battles or queue productions in cities, after communicating this between everyone in the game and we all only hit end turn when we were all absolutely done with our turns we ceased to experience desyncs outside of someone getting a ping spike or clientside lag.

Especially after figuring this out we had a rare never before seen case of the game desyncing on a lag spike and resyncing on its own the next turn.

I've also noticed that sometimes units are not synched and the other player can just do whatever like the units didn't exist in his map if the units have been spawned the turn before so potentially has more issues than what we realise

The achievement for playing with a human player on steam has a 0.7% completion rate, but this achievement only triggers when you finish a game with a human player, I think that speaks volumes about how bad of a shape the multiplayer aspect of the game is in, because I see boatloads of lobbies on the multiplayer connect window no matter what time I play the game but very few people are managing to play to the end what with having to rehost lobbies multiple times in a 3 turn period, nukes softlocking the game, certain AI units softlocking battles which softlocks the end turn button and so on. One would have hoped for a hotfix for some of the most egregious bugs by now but I guess we can hope Amplitude are packing all their croissants in one bag and we get a massive sweeping fix in one big patch or something knocking out a majority of the issues in the first month of release, cause' its been almost a week now.

This issue is a nightmare. So many wasted hours. Repeated turns. Messages saying 'connection lost. The host has left the game, or you have been disconnected from the game server'. Crazy that the game has launched with this serious multiplayer issue. Clearly an issue with Humankind as nothing else is effected and we never have these kinds of connection issues, especially when we are playing in the same room.

yes, i agree. got a bunch of friends who played civ and hopped onto the humankind train when we saw it, loved the combat systems and figuring out the mechanics but goddamn the amount of desyncs and disconnects is quite abhorrent. a couple of turns in and we all drop, tried to reload and one of us gets disconnected during the loading process. 


getting really tired of the unplayable state of the game right now.

Thanks for your upvotes and ongoing support.

I really do not care much about player statistics. as said in the OP Humankind has many issues and it is upon the devs to triage and prioritize.

Among the issues in MP, which is part of the advertised featureset, imho this has the highest priority, I hope this makes it clear that this does not mean it has the highest total priority over all issues reported. 


Please keep share your point of views and experience while reporting the issue in majorly this thread with savegames and logs. 

I am #NotADev but I know that few logs from few people could be too less to find a repro of this issue. More cases and logs are never wrong.

Thanks @The-Cat-o-Nine-Tales for the new optional beta patch. 


We will try 1.0.2-116 and report back this if will solve anything about the reproducible desync issue at every turn as reported here


@Stealthkibbler "Something that caused desync without fail in a game I played with friends is when someone pressed end turn and then proceeded to order units around, start battles or queue productions in cities, after communicating this between everyone in the game and we all only hit end turn when we were all absolutely done with our turns we ceased to experience desyncs outside of someone getting a ping spike or clientside lag. "


this is an absolutely brilliant discovering. I had no doubts that sometimes I was able to press end turn and then I could move still some units.

Why? This also happens in Civ for decades, it is like you have 2 turns in a turn. Not sure if you know what I mean. 

With the beta patch we will try to avoid this but also enforce it to see if there is any difference. 

If it does not happen this would be a feasible workaround. tldr: I can confirm sometimes after end turn you still get some idle units shown and move them like in Civ 5 and 6.

@Stealthkibbler  @Lt_Miles @The-Cat-o-Nine-Tales seems I have great news. even though the MP sync fix is not included in the beta patch notes, I can report the following

1. turn with the beta patch the game was still desync as before after end turn for both

2. after this the sync issue did not appear for 7 turns, which is an remarkable leap forward from where we come from.

3. Seems like Stealthkibbler has found the possible root cause. on turn 7 it went desync again. 

How to repro:

- 1 move a unit

- both players press end turn while the unit is still moving

- game desync on the begining of this turn. After end turn the player should not be able to change anything except scrolling the map and view things. This seems to heal it.

If this is the cause it would also explain reports of others that also other of your game have this issue. but it can be easily fixed by locking moves and building queues.

I have to thank you for the discovery. Since the game is nearly stable with the beta patch. 1 internet connection lost after 12 turns and 2 desync of which one was the one avoidable above.

It seems now clear how this reproduces.


1. you may not move any units after you pressed end turn

2. you may not change anything in cities queues after you pressed end turn

3. you may not press end turn while units are still moving.

when does this happen? you move the last inactive unit. see example in the screenshot:


4. avoid long moves that span across turns, they can (rarely) cause issue in #3 


a. move all units (according to the icon of idle units)

b. hit end turn

c. instead of waiting for other players (turn pending), another time "idle units" icon appears. 




Even if you do not move them but skip their turn and all units are skipped (mostly 1-3 units affected) the game will be desynced on next turn.

honestly i would rather they would prioritize the stuck on loading screen error... some of us can't even get to the main menu, despitze all the fixes listed everywhere!

@Techadept it feels you are frustrated about it and it is very understandable. What do you think about posting this in relevant bug threads for this particular issue?

In 12 turns 1 desync and 1 dc is still pretty unstable. But good to know on a workaround.
