hi I’m in 4.19 and lately I noticed when I put a nav mesh volume out the floors turn green , in fact when first putting the volume out , there is a green square under it , then if you scale it up I guess the green square scales with it. it disappears when you play in the editor however. but the green sits like a couple feet above the original floor mesh. Almost up to knees on characters. has anyone seen this before or is it just me? thanks
