Flameblast causes player crash to desktop.

If I am in a group with someone and I use flameblast on one side of the map and they are on the other side, they will crash to desktop and I won't. I have tested this enough to know this to be consistent.
Playing as bloodmage with area effect scaling heavy
Seems to occur on fully charged flameblasts as opposed to partial charge which from my testing didnt seem to cause crash to group members.

Adding also that i mostly use flameblast with the solar orb for the faster pops. It is setup forignites and the ignite corpse explodey support
