So I have a save game I have loaded and reloaded, including going back 2-3 turns and the game never progresses past turn 80, it just seems to hang.  I don't know what is causing it but it's shame because it was going rather well.  Is there somewhere I should upload it to figure out what the bug is so it can be squashed or not worry about it?

Hi,

You should definitely report the bug and attach the save, infinite turns is something we're keeping a close eye on. Either here or directly in https://www.games2gether.com/endless-space-2/forum/73-tech-support.

OK thanks!
