building doesnt need place to be buildable

[emil23]

hi i received my map from my friend and i see that now when i make builings with worker they dont need any place to be buildable i mean i can build them everywhere on other building aswell. i was pretty sure that colision size is 0 and changing colision will fix it but when i went editor i realised that colision is fine and everything else too so wtf should i change??????????? sadly i cant ask my friend what he changed

Check: "Pathing - Placement Requires", and also "Pathing - Pathing Map". The former should be "buildable", and the latter should have a texture for pathing in order to prevent ground units to walk through it and/or avoid other structures being built on top of it.
