I'm trying to make an energy drain ability, animated with a continuous beam from the caster to the target. I'm pretty sure the actor event handling mechanism has somehow gone into an infinite loop, but I can't spot my mistake. Could anyone take a look?

Yes, this will probably lock the game up if you try it out, you have been forewarned.

So it appears that it wasn't the actors causing the problem. I deleted both the attack actor and the beam actor and it still freezes. The only thing that needs to be present to cause the freeze is the create persistent effect starting.

I'm completely at a loss; it doesn't even reference any other IDs. This should be pretty simple, right?

Ah hah! Do not check Persist Until Destroyed unless you have a periodic effect. It will cause the game to freeze apparently.
