This is a new game with the newest version of GC3 with all the DLC. I am using mods and am playing against random factions. Here is a summary of what happened.
Yesterday I was playing, and the game froze. After I did some things the game crashed. The crash manager generated a crash report and sent it in. I wrote a short note on the pop-up window that now appears.
Today I started GC3 and loaded the last Auto-Save. I did a few things in that turn and clicked Turn. GC3 froze while displaying it was processing Unknown Player 10. I waited a while (exact time unknown), then saw GC3 and Steam both crash. I hadn't done anything except watch. No crash report was generated or sent.
I decided to turn off the computer, then turn it back on. I restarted Steam and GC3, then loaded the same Auto-Save. GC3 froze again at Unknown Player 10. I timed the wait. After 11 minutes and 27 seconds, GC3 crashed. Again, no crash report was generated or sent. Steam did not crash this time.
Just to be sure, I ran GC3 again, loaded the Auto-Save and GC3 froze again as before. I used Alt-Tab to get to Task Manager. I did some things and nearly everything froze. The cursor would move, and I could hear GC3 ambient music in the background, but nothing else worked. I didn't want to wait, so I manually forced the computer to shut off.
I sent in Ticket #USQ-571-53698 with a lot more information and files.
