You have to select the ragdoll that had an animation done on it and load the proper model from the list. Do it for every model that was animated.

flaming cookies, load has different objects saved, to load you have to choose object, and choose object's animation object in load menu (example: if heavy was animated, choose heavy.mdl, if there were two heavies, heavy that was animated/added_to_world secondly will have aditonal symbol after ".mdl" ) , voila! object's animations are loaded!
you have to do it with each object that was animated

i recomend you to also make gmod saves along side SMH animation saves, it will have object's possitions and other stuff alreadyy loaded (including ragdolls and props)
if object is not loaded, then you have to spawn it again in spawnmenu, that's another reason to do that ^_^
