thanks to jukkis for various 3ds
@Parpalou, you didnt get stuck on a 2d barrier but on a wall of a inside out house of which i flipped textures manually there are quite a lot of those and i could not figure out a way to move edge of house in cfedit
Noooo ! Check carefully all your 2D-barriers cause I did not do something mad but got quickly stuck.
You could at least check where we all got stuck and correct them for all these places.
