So I made some custom materials for my map, and whenever I load the map from the save file, the custom materials are the pink-black texture. However, if I load them up in the material dialog, and click 'reload' it fixes it, somewhat. I have to click on the brush with the texture (after reloading it), click on reload AGAIN, and then apply the material. I can still compile with these errors, it's just that it's REALLY annoying. Has anyone else had this problem?
