Regarding 1.1 beta 3.014...
In a gigantic galaxy with six major opponents, the game made the following errors after 5 hours:
--Espionage funding suddenly disappeared
--Unresearched parts of the research tree disappeared
Probably a bunch of other things also. I played 4 more turns. Alliances showed up after Interstellar Government was done so apparently the game was still aware of the tree. I suspect espionage was still working as well.
I saved and played again 2 days later. Everything was back.
I have an ATI 9800 Pro. My case is well ventilated. Temperatures were normal.
I probably won't have another marathon session until Sunday afternoon so I can't repeat the situation. In the meantime, I updated to .015.
Peace.
