Here's another desync, this time on turn 1.

1. My partner ended turn 1.

2. I ended turn 1.

3. Immediate desync as it started to compute the turn.

The only real difference with this save versus the previous games is that this is a colossal galaxy size with 8 players (2 human, 6 AI) and a dense galaxy.

Since it happened on turn 1, I don't really have a save file for the turn prior, only the auto save that was generated for turn 1.

Ok, I have a desync (turn 32) with the save files this time. I included 3 autosave files (Turn 31, Turn 32 and Turn 33)

The desync occurred with the following sequence of events:

1. I ended my turn and waited for my partner to end her turn.

2. While the turn was ended, I was inspecting my colony.

3. I decided to add the money building from AstroFinancing to the queue at the same time she ended her turn.

4. Immediate desync on clicking on the money building to add to the queue.

I recall Endless Legend had the same desync issue early on when trying to modify the construction queue during an end turn event. Perhaps it's the same issue here? In any case, hope this helps. I'll post again if I find another desync with different repro steps.

Thanks, I'll pass this on.

infinite turn pending @ turn 51 in our 8player mp game. after that we couldnt load the save (not even turn 47,48,49,50) , whole game is lost. i ll try to find the save , but it seems its not in my folder, maybe because its autosave

something was happening with space/ground battle.it said i am in encounter , but i did not see that on the screen. all i had is a fleet which cannot attack because "space battles is already going on in this system"

there were 3 fleets in the minor faction system:

mine (Cravers)

pirates

another player's

i cant produce a screenshot because i am unable to load the save

EDIT:  i think this is the save AutoSave 1911.zip

Unfortunately for me and my partner, we experienced our first desync on this preview patch (1.0.11) by turn 5 and our second desync by turn 15. It always seems to happen while resolving an end turn.

That said, I was being hopeful though so I wasn't being as cautious as I was in 1.0.5 with the things I would do to prevent desyncs. Specifically, in 1.0.5, as host, I would never end turn until my partner ended her turn first. The reasoning behind that strategy was that I found that if I happened to be in a screen or panning the view when she ended her turn and the AI started to compute their turns, it almost always resulted in a desync. By waiting for my partner to finish first, I could click end turn and just not touch anything while it computed the end turn. That seemed to help us dodge a good number of desyncs. In 1.0.5, it certainly felt like we didn't receive desyncs til around turn 30ish, so its hard for us to gauge if there was any improvement at all on the desync front with this preview patch.

I notice the damage display error on basic slugs isn't listed? Unless I'm overlooking it.

• The technology helper is now active only for human players.

Would be great if there is an option to disable it entirely. Not all human players need it.

EDIT: The reason why it should be optional is that, apparently, the technology helper is a very intensive and complex calculation that has an impact on performance.
