I still cant build multiple dugeons in the same level. intanced or not… they jsut destroy each other. in editor or at runtime. doesn’t matter. 
Oh and @ - I would apriciate a tip. I nedd to do “adjacent cell emitter” backwards. so mark rooms how far away they are from nearest wall, to place proper roof tile. I’ve made a few dungeon rules myslef already but I cant get my head around this one somehow
