So I've had great fun using Asset Editor (https://github.com/donkeyProgramming/TheAssetEditor) with Troy and Dynasties, and I decided to go back to Rome 2 and have play at kit-bashing some new uniforms and outfits there too. Only problem is, when I apply them to a variantdefinition and try and load the modded troop into a custom battle, I get an instant CTD. I've done a bit of trial and error, and I'm fully confident that the kitbashed model is causing the crash- I just don't know why.

This tutorial video (https://www.youtube.com/watch?v=Bw-FjWh2Ps8) implies that Asset Editor was at one point compatible with Rome 2, and the link in the comments takes you to the download for the newest version- .47- which I'm using.

I've posted on the github page, but I thought I'd post here in the hope that someone either, a) has run into the same issue and knows what I'm doing wrong, or b) can point me in the direction of a more comprehensive and detailed tutorial.
