Unknown mod failure

The only thing I can tell you is to retrace your steps. Undo the changes and re-apply them one by one to see what's afoot.

Moved to modding questions

I've managed to solve this problem. For some reason moving the battle_models.modeldb file into my vanilla data folder caused this problem. After I put it back into my mod folder my mod worked fine (all the new units were there). However the game used to work when I had the battle_models.modeldb in my vanilla data folder.

Has anyone else had this problem?
