I am getting this error after trying to convert a JKHub map: LF - Arena de Duelos - JKHub I only used GTKRadiant to see the coordinates for spawn points. Entity modding I did through text files and compiled into bsp. I also put a .siege file from another mb2 map as well as editing .arena file to have type "MB" yet it still gives me this error. Does anyone know any potential solutions? UPDATE: After trying to find the solution, I no longer receive this error but instead now the map starts loading then crashes and says "ERROR: Bad index in triangle surface"
