I ran into a case where the Ideology screen would not allow me to exit.
Here are the circumstances:
- Benevolent:
- The root of the tree had been unlocked
- Benevolent points = 30
- The next items cost 29
- Pragmatism
- No items unlocked
- Pragmatism points = 20
- Malevolent
- The root of the tree had been unlocked
- Malevolent points = 22
The unlock and done buttons remained unselectable no matter what action was taken. Further, <esc> or other keys would not allow exiting the interface. I had to kill the GCIII application in task manager to exit the game.
FWIW, previously I also encountered crash when interacting with the benevolent interface. However, no crash dump was generated. Moving to an auto saved game, then proceeding from a saved point allowed for making it past the crash point.
