[vJASS] (Yet another) Instancing Issue

[ArpatronEvilDrac]

EDIT: Resolved. Apparently it's bad to RemoveLocation something you're going to use.

I've sort of coded myself into a weird position here. I tried using a correctly-functioning spell projectile framework and added on functionality (calls an aoe-based struct at the location of the projectile.)

The projectile framework worked fine, but the moment I added in if's for whether it's an aoe, or set it to aoe on death, something changed. I literally can't figure how this crap would affect my instancing.
