Instant crash with witch in party using flameblast and solar orb.

Playing with a three or two man party, one witch (me) and two others. If I'm close to my allies and cast abilities, nothing happens. But if I use a single ability off screen for them, they both crash. Doesnt matter if I'm in a two or a three man, when I use abilities offscreen for my allies, all of them crash.
