when i try to start to play my map the game crashen like when is 90% done loading, i dont know if i made something wrong with the ugx script placer v2 but everything works perfectly, no alien text, main menu custom screen, the map is not finished yet but the spawn points, the zombie spawns, debris, weapons, perks, box, pathnodes, reflection probes, etc. the basic stuff is in there so i  hope i can fix it 

are you getting any errors?
