Bug description

My death consistently causes the game to crash.

Viewing my corpse often causes the game to crash.

Other people on the server can also crash upon viewing my corpse, but being next to me when I die does not trigger a crash. They have to specifically look at my corpse to crash. This was tested a few times.

Interestingly no one else's death or corpse causes any problems.
