I'm trying to remove lightmapping from my terrain but no matter if I delete the lightmapping, uncheck the box to apply the lightmapping, ect. (which it does remove the lightmapping but as soon as I enter into gameplay the lightmapping will reapply ingame and then back into the editor window ). The only way to get rid of it is to disable lightmapping through code but that still means that it shows up in the editor window. It's really annoying. I figure this is probably a bug since it's not...
