Probably this question was already asked in this forum, but I'm unable to find the answer.

I have systematic CTD when trying to continue a saved game.
I save one campaign in an early turn (about 2-3), and I'm able to continue until at least 20-25 turns without problems. However, if I reload the saved campaign, it CTD in the rebels turn when I press the turn end button.

Any idea of the reason for this kind of CTD?
