that is the case for me too, same bug. and how did you unbugged bonemass? or did you summon a second one?

That was a while back. I don't recall exactly. I started shooting him with the bow and moved away from the tree and I think he eventually just fell down. (like maybe he tried to follow me and unstuck himself??) I should go back there and try to summon him again to see if the same thing happens.
