The biggest problem I've encountered so far is dealing with Joint Controlled Morphs :( I'm currently trying to Tailor the JCM's from StephPetite onto a new garment, but Tailor is wacky and makes neighboring morphs were none previously existed in groups. Then you gotta hack the cr2 and add the code to make them cross talk and fix names and on and on...no longer a quick and easy process :(
