Towers do damage to friendly Towers!

I think u kno the problem:

I make a TD and have towers with splash area damage... Now they attack my own towers if the enemies they shoot on are coming into the splash-area range to my other towers... The other towers are then given damage by my splash towers... I already tried to handle the prob by clicking adding "Enemie" to "Granted Aims" ( In unit-editor ) ... But it doesnt work

"Ally" isnt clicked in "Granted Aims" ( In unit-editor )

Try changing the Combat - Attack 1 - Weapon Type from "artillery" to "missle (splash)", the first one deals damage to all adjecent units and is used by siege units and canon towers, while the other one only deals splash damage to enemies and is originaly used by demon hunter in demon form.

Or change the targets that the splash affects to enemy ground.
