CygnastyLooks like you've got to update your UGC whitelist preset
This is why any league admin should contact me after generating the new whitelist for their season, I can update the preset to the new ID, everyone then downloads/sees the newest version of the whitelist for their league and game mode.
But UGC seemed to be kind of childish in their responses when I asked them anything about their whitelist. The new one should be http://whitelist.tf/109 (and your url needs some http:// in the tag)
