heyas; this is a toughie. :/ what were you doing between this latest version and the previous version? i mean, were you joint tweaking, messing with the setup bones, or what? if you figure that out, then you'll have an idea of where to start looking for where it messed up. if you were only doing jps, you could splice them into your old pz3 fairly easily. (tediously, but easily.) also, did you save the pz3 while you were in the setup room? i think that's a bad thing. oh, also check the setup room and make sure it isn't doing something bizarre like showing only unboned groups or somesuch. dunno much about the setup room... but can't you just use the grouping tool in the main room to re-do the groups? (probably not, right?)
