I also noticed yesterday that if you open a figure in Poser that is non-figure:1 and then save the set it will make it figure:1, and point all the internal references to figure one. But it has to be the first figure opened after Poser was started, if any other figures were open first, even if deleted, another number will be used when the set is saved. This can save the labor of editing the CR2 back to figure:1, which is part of the requirement to get the null loader to work, incidently. Anyway, I think the easiest way to fix this mess in Poser 5 would be not to allow cross-figure-linking at all, which would of course mean full body morphs would not work as intended, but this would be a small sacrifice to make. JCM morphs should still be allowed to run from the same figures parts. That is to say figures would only reference themselves. CL could perhaps even to this as an update to Poser 4 and PP.
