HTC, I tried to attach a .res file with an in air spawn that works offlline, but crashes when you try it in a custom arena. However, this is not allowed, but .mis files are allowed. Could you change it so .res files are allowed? A .mis file would require everyone to open it with mission editor and build res. I can use the resource uploader, but it will crash in the custom arena and I have no way to warn players not to use it in the custom arena.
