Like most computer-related things, always think, "If I do X, what will happen to my project", such as "If I that new piece of clothing, will Poser give an error about an obj file that isn't there and delete my character?" The solution: 1) Before applying ANY pose, go to Edit, then Memorize, then Figure. If the pose wrecks your character, go to Edit then Restore then figure. 2) SAVE, SAVE, SAVE. If your character is important, ALWAYS save the file before changing a pose, adding clothing, and so on. 3) Go through ALL of your poses: apply them to a stripped V2 (or M2) and then save the poses to the library without morph information. Why do merchants save pose files with morph information? Ask the merchants who do this. Ask the testers who don't catch this (or who allow it to go through, untested).
