Yeah, I've had the same issue since release. I can usually play for quite a while before it happens. When it happens, I Ctrl+Alt+Del and have Windows force the game to shut down. Then I reboot and restart the game to continue. Since the game autosaves every turn, I don't lose progress. However, it would sure be nice if they would fix it. They probably have no idea what is causing it.

I can say that it happens more when I edit a lot of ships. I have a suspicion that weapon effects in the ship designer may be aggravating the situation, but it's impossible to really tell.

I have Win10 with an AMD Ryzen 5 2600 and 16GB of RAM, and a Radeon 480 with the latest drivers.

I have been having the same issue for months now. It seems to be linked with having an AMD GPU (got a R9 Fury).

Spudbynight what's your video card ?

Hello. Same bug here. I tested the game during the free weekend, and this bug never happened. Then i bought the game and it is when the games started to freeze, after doing one thing or the other. I can't find a cause, but if i run steam in offline mode, then this happens maybe 1 time, then the bug doesn't happen in hours.

Hello again. Definitely something is wrong with the game, because the bug is happening more and more frequently,  to the point i am getting really pissed with the constant alt+F4 and reload. Can anybody point me to the closest tech support agent? thanks.

Hello. I found a way to stop this from happening, but it gives more questions about if it is really a bug or something intended.

I did a check up in all game files integrity, and since them, the game stopped freezing. But i cannot be sure, because i've been playing online, and i had the issue both when steam was in offline and online mode. First thing i thought was the cause of game freezing was online, due to a conflict with the serial number, since i bought a cdkey in official store, but i had the feeling it could be shared with someone else, yet. But now the game is running smooth again.

So it went this way:

Installed during free weekend promo "endless space 2"-> game ran smooth.

Promo weekend ends, game is locked. Then unlocked with cdkey -> freeze bug

Checked game files integrity -> bug vanished, at least playing 24h without more freezes.

Hope this throws some light over the issue.

That can't be it, because I verify file integrity regularly, and I have reinstalled the game a few times due to upgrading computer, etc. I also purchased the game at launch.

Having the same issue, it is truly a pain. Would very much like any situation anyone has on the matter, short of a fix from the devs (but considering the bug is a bitch to reproduce, i am not holding my breath).

Is that really a bug, or a consequence of my bad machine specs? By doing what you said, do i really get rid of this bug or... its innevitable since IDK how the game even runs on my machine? :(

I have an excellent computer, and this bug has plagued me since the game was released, so it's not your computer.

As long as I remember there were issues with AMD Radeon drivers in  the past, too. Sometimes it was useful to roll back the driver version. Amplitude did reach out AMD for to fix the driver issue in connection with Endless Space 2 and it was fixed. What about to make a new thread and to deliver the requested files listed here Tech support guide ?

Latest driver trouble (not showing some graphic effects in combat) was fixed with driver version AMD 18.5.1, past Amplitude did reach out to AMD.

My guess is, it's worth a try to upload the requested files (link above) when game freeze occurs in a new thread and to roll back to driver version 18.5.1 then to check out.

Or the other way around, to (re-) check if latest drivers (in case of Trifler and ColonelPlastic - the only who offer information about graphic cards in use here) are installed:

Latest driver for AMD Ryzen 5 2600 -> Driver AMD Ryzen 5 2600

Latest driver for AMD R 9 Fury -> Driver AMD R9 Fury series

Two things that helped me (R9 390, Win 10)

- disabling Steam Overlay

and

- running the game in borderless window mode

Switched back to 18.5.1 driver and this doesn't fix the issue.

Also, disabling steam overlay and switching to borderless window mode doesn't fix this either. 

I've just managed to play 10 turns before this happened again. 

The whole thing is very hit and miss. I can play for a few hours without it occurring. Sometimes I can go 10 mins before it hits.

No dice here either. Massive Alt+Tabbing does not seem to affect it either, so I don't think it's related to needing to redraw the screen.

I don't have issues with cooling. I'm running some pretty frosty temps as things stand.

My AV is Avast if that is a potential common factor for anyone else.

No temp issues here. Running Windows Defender.

Today, for the first time, I got a crash dialog box after the game froze up. So, I'm attaching diagnostic files. The directions say there are two places to get the output_log.txt. I'm guessing that means they're both the same? Hope this helps.
