So we ran across this person in a boat and apparently she died (must've been boat-sick).
We managed to drag her out producing a funny but small and not really important visual bug (she stays like in this pic (standard 3d model stance) above your head). However we couldn't lift the boat. I decided to cut my losses and take the body home, and after teleporting the boat teleported with me (as if her model was still stuck on the boat, but the boat landed on my HF and I still couldn't lift it).
You see on the left her rigor-mortis'd body (hehe) and on the right the boat on my HF, except we had to destroy it to get rid of it. After we did so her body seemed to dissapear in thin air. It's quite strange. Hope this gives you a clue as to what happened, if not, well, I don't really have any idea what just happened. But we fixed the problem ourselves, it's just that this was rather annoying waste of time
