Tested out useabilityonplayer, and it too un-queue's a spell when changing targets.

I think that's kinda lame, TBH, but not game breaking...

You could technically cause a loop between two objects to keep trying to cast a spell until it shows up as currently casting, but I dunno if that would cause lag or not, lol. Plus it would be dangerous if you decide to not want to cast that spell after pressing the button. Unless you have ESC set to cancel spell casting, or you move... lol, still a bad idea. I dunno how smart you'd be able to get with it either.

Do a smart queue? Set a variable to currently casting spell, wait for that variable to be different (as in not casting) and then issue the spell cast. That's like true queue'd casting with no clearing.
