Ok I am making a dod map that has a destructible mortar with TNT. When the TNT is set it triggers a multi manager which controls the sound, counter sprite, messages and such, as well as replaces the model with buster mortar via env_render entities. One thing I can't figure out is after the mortar is broken the func button still works and allows a ruined mortar to fire. How would I disable this on mortar destruction?
