I tried to replicate it by sending the same army into the main fort in the center by clicking behind the door and it didn't freeze, so I agree with you, it doesn't seem to be that. As you say, very strange.

I'd like to attach save files so you could try it yourself, but after I managed to get past that section I got overexcited and stupidly overwrote the save. Maybe tomorrow I'll try playing the level again from the start and see if I can replicate the bug.

Hi Stefan. You might remember me from the other bug where I was having a different problem with level 13. Since I got past that part, I've now run into exactly the same problem Jasper is having. I'll attach my logs and saves in the hope that it helps.

Thanks for getting back to me so quickly.

I tried forcing it to single GPU rendering in NVIDIA Control Panel, but the outcome was the same - it still froze at the same point. However with a bit of experimenting I did find a way around the problem - by setting the rally point outside the doors instead of inside. There was a bit of slowdown, however after breaking the doors I was then able to get inside and set about breaking all the AI's stuff. My army is quite large as I have been converting all the incoming waves so I have well over 100 creatures at this point. I suspect it might be an issue with pathfinding so many entities at once. As I said it didn't happen when I went into the crypt area, however I have taken on a few more recruits since then so perhaps I've gone over a critical number. I can't think of any other explanation.

Also my system info is as follows:

OS: Windows 10 x64

RAM: 16GB

CPU: Intel Core i7 6700-k

GPU: Geforce GTX 970 x2 (SLI)

WFTO build: 1.5.0f10
