i dont know, Annie, but I dont think so. Jwear is a short outfit, so it really out to do well....if i get a chance, i may convert it to see if i get the same trouble you had with it, cause it maks me curious.   I have converted several Aiko things over to v4 with no trouble.  The only issue I have ever had is when converting the elf dance set, and then it messed up on the feet area only, but that isn't a real issue, since it says it doesn't cover feet, lol...But being me, I tried it anyway, lol.
