It's weird that it shows up in the preset maker, but not in-game itself.If this is so, there might be a problem with the exporter. I've heard of instances where the preset won't show up in the game after exportin' 'n the like no matter what one may do. However, the problem seemed to have fixed itself once those who have endured the problem re-downloaded the game so ye' could try that out. Be sure to save yer map/preset/texture/etc. files in a separate folder beforehand though so ye' can just move them back into their proper destinations once ye've re-downloaded the setup files.
