HEEELP Trigger causing fatal error only in multi

I have a trigger that when used, spawns 8 units to cast flamestrike in a clockwise pattern around the center of the map. I have edited flamestrike to make it a non hero spell so the unit can cast it. The spell works fine in single player, but for some really strange reason, in multiplayer the spell will give everyone in the game a fatal error as it finishes. It will go through its entire cycle only to crash at the end... Why is this crashing??? argg.... so confused...

Here is the trig:

I have the ability changed as follows: Mana cost set to 1, damgage increased, cooldown to 1, and it doesn't effect friendlies.. Thanks for help.

jebus, couldn't that have been looped?

er, anyways, i have no idea, except that i don't trust waits

Well I don't think its the waits or anything... The spell works completely in single player... but in multi it just quits the game.
