Mark / Dash sometimes crashes game.

The Mark / Dash spell causes my game to crash if I reappear at the same moment my target dies. Afterwards I lose connection to the server and am unable to reconnect to that game even after restarting the program or my computer.

This has happened 3 times to me sense the Mark / Dash spell has been added.

I have been unable to get a meaningful screen shot or video of this happening.
