I got the same crash, I was told in the "bug reports" discussion that it is a mod conflict (I am only using this mod so that's not possible), missing dlc (I have all dlc), or broken installation (unsub and resub, which I've done several times and still get the same crash). I've noticed it happens more frequently the longer the game goes on, it started for me at about 1944 and then randomly decides when it will crash. The author has not been very helpful with this problem.

This person was using incompatible tech mods. There are no such errors nor crashes for me no matter how long the game runs, and while the error should not cause crashing, it indicates the tech trees in your game setup are not working for those 3 reasons which can cause crashing. Resubbing does not always fix installation issues but it's hardly an issue I can investigate on my end. See post 1 in the bug thread.
