Rodents by AM export problem

Doc Acme

I've been having really great luck converting & exporting via FBX for furred, LAMH animals until I tried an older one with the European Grey Squirrel,or rather the Rodent Polymorph.  The end result is the base figure isn't fitting to the fur items and I can't really see what's particularly different with it.  It seems to be some sort of morph or transformation issue though. Figure is zero posed with the exception of the Jaw opened 1/2 range.

I DS, I've tried every combo of baking, memorizing, etc. but doesn't seen to have any affect.  Not having proper docs for the process of course doesn't help.  Hoping someone might know what I'm missing here.

If I remove all the fur objects & just export the squirrel w/ same settings, it seems to come in correctly.
