I have a bug where during the computer turn, the game locks up. I am running 1.10[b4].018. I am about 3 years into a great game. The autosave, prev auto save, and the most recent other save all have the same problem. I am not using mods. I still have control over things as you would during an end turn, just that the next turn never starts.
These are from my error log:
Debug Message: Arcean Freighter M2-1 1341 has no trade route. -- there are a ton of these. I suspect this is it. I don't see it in the acrean ship list in the diplomacy menu, otherwise I was going to try and buy or trade for it.
Debug Message: Error flipping back buffer to primary buffer.
Debug Message: Device lost
