Repeatable bug. Save file available. Debug.err file available. User-initiated crash after interminable delay.
Have an odd bug. When research on Antimatter power plants concludes, the turn never returns control to me, and the GUI does not allow its usual interaction during turn processing.
If I research a different tech to conclusion, the game continues as normal. If I return to Antimatter power plants, it repeats bug behavior.
Workaround is to not research antimatter power plants to conclusion. I have not yet tried getting it via trade, as I am far ahead of the competition; not sure if this would cause bug behavior or not.
Any help is appreciated. I can provide save file (10,225kB) and debug.err (22kB) file.
