Roof problem in official mapper

[Skynet]

I have an annoying problem with the mapper. Example: If I make a house and room to it, I can turn on and off the roof via the button, BUT if I save the map, exit the editor and then open it again and load the map, the roof doesn't show up!. Clickin the roof button doesn't help, but if i press F8 to enter play mode it shows up. Any fix for this problem?

Maybe you need to turn on the roof before saving?

I had that problem, you have to save with the roof first, and you may not enter game mode ( F8 ) in the editor before saving.
I think that was the way i fixed it, or well just paint the roof again.
