Has anyone come across this error and found a way to fix it?
When i click end turn the game runs through the motions and when it comes to finishing all other AI moves it freezes and then after a minute the game comes up with this error and the games just crashes out to desktop.
What is stranger is that it is doing it with every games save i have so it just not down to one save.
I have verified game files and still nothing.
This seems to be a Low Level Fatal Error and have looked through the forums for a fix but cant seeme to find any specific to my issue.
Any help would be grateful.
