I made another game, everything went smooth this time. Until around turn 150, the game stopped on computer's turn. Everything looks fine, mouse works, cursor is animated and music is playing, but the computer's turn never ends.
I actually had these same symptoms (stuck on computer's turn) on a quick game with v6 b8, between turns 108 and 109. Switching to strategic view didn't seem to have any effect. The binary was pegged so it may have been spinning or missing a loop end condition. Is there any way to see if it was within the mod or core game?
