Yeah, i know, this is another error of sapien, the thing is im developing my firfight and it has 3 bsps, (n35, n20, n35a) the problem is it compiles fine, but in both the game an d sapien when i switch to n20 it crashes, the last thing i done was changing some shader and some new scripts, but i delete them and still happens

heres my debug
