Few question system wise. I've tried a few things, but I'm wondering what you would recommend.
The one I'm experemting with right now is just calling the knockback again on the unit, in the same way that's it's called when you cast a spell. This works, but there is still a unit/group that I'm not removing somewhere (occasionally on casting, it teleports a unit that you've previously knockbacked/collided with to the target loc).
