Well, there goes my 2nd campaign

[IRONxMortlock]

What unit causes the CTD?

I have a CTD in my campaign as soon as I select a particular generals bodyguard, but I'm able to get around that by just never clicking on it. Selecting the stack still works. Maybe it's not that simple for you.

I really hate to be forced to give up on a campaign like that :/ Happened to me a few times with some mods in previous games.

In both cases it's a general. Unfortunately ignoring it won't work. In my previous game I thought I'd try that however then it would CTD whenever I'd declare war (or if someone else declared war on me). Can't disband.. CTD. Can't conquer a nation... CTD. The trouble with the unit appears to be just the first sign of the problem.

Just because its software doesn't necessarily mean its the ETW program thats at fault.

And just because you haven't experienced this doesn't mean that it's not the software's fault. Maybe you didn't conquer things in the same order, or produce a general from a "CTD" city? Who knows? I'm sorry, but outdated graphics drivers etc.(which isn't relevant anyway... I'm up to date) will not be the cause of allowing me to play the game perfectly for 120 turns and then suddenly make it CTD whenever I interact with ONE particular unit or declare war (as Servius1234 describes). It's most likely some kind of save game corruption. Thanks for you help anyway though, I appreciate it
