I´m not sure if it´s a bug, but last time when I teleport to a Player who ask me for help, I heard my death-crying while I still looked to my own house.
One second later I awake on the top of his open Castle-Gatehouse and viewed my own gravestone.
I guess, this is a very rare Situation (still decreased some of my skillpoints). But maybe it is possible to remove this GM-Trap.
