Since Patch 2.1 I randomly experience a problem upon teleport or return.

The game suddenly slows down extremely during the teleport cast animation, and before I see the zoning Screen I get "Final Fantasy stopped working". I had this happening like 3-4 times yesterday and 2 times today. When I Zone back in, I appear at the Zone I wanted to teleport / return to.

This only occures when porting or returning with the Animation, not happed (yet) when I return from being K.O.ed.
