I have made 4 different maps, 1 main map and 3 other maps connected to it. I didn't notice I mixed up the gates somehow and ended up having to fix the gates, Once I did that and tryed to export the main map again it ended up failing. I entered the map, As I still had the files from the first time I exported it and i'm missing three meshes from my map. Since I cant export the map again because it tells me it failed I cant fix the missing meshes. To sum it up I need to know how to export my map again without it failing.
