Actually I just had a similar problem recently with a figure I'm developing. It may not be the same since you can see the left forearm but here goes. It could be a cr2 file problem. in the character folder find the robots original .cr2 file (not the new one generated from saving to the library) and open it in wordpad or some text editor. look for a line similar to this one figureResFile :Runtime:Geometries:Cave Goblin:Goblin.obj There should be at least two such lines in the cr2 make sure BOTH of them point to the same .obj file located in the same place. If the first one is correct and the second one is different then it will never save right even though the origional will load correctly.
