I'm having a problem where the Unit Editor keeps crashing when I add parts to a unit. It seems to be both random and specific parts that cause the crash. For example, when adding Achievement Crest 3 & 4 to Katana Samurai it crashed. Later, those two worked but the 7th crest caused a crash. This happens with various parts added to various units. A couple weeks ago it was working, I had no problem adding any part to any unit. I can't think of anything that's changed on my PC to cause the problem.

I've tried reinstalling both the modding tools and Shogun 2 itself, but the problem persists. I also tried running it in different compatibility modes but that had no effect. It crashes both with and without the unofficial assembly kit patch. It also didn't help running as administrator. I've run out of ideas on what's the problem and how it can be fixed. Any help figuring this out would be appreciated, thanks!
