Ok... I tried it again and it didn't crash. Weird. And it crashed like, 10 times when I tried it earlier today. Now not one problem.
EDIT: It crashed again. But this time it crashed after this:
*** CREATING MISSION
*** Stage 1 create
Add-Ons/Bot_Hole/events.cs (582): Unable to find object: '31016056' attempting to call function 'getClassName'
BackTrace: ->createServer->createMission->[Slayer_Dependencies_Brick]onMissionLoaded->[Slayer_Dependencies_Minigames]onMissionLoaded->onMissionLoaded->[BotHolePackage]startGame->createHoleBotList

//Crashed here.
I really have no idea what's going on at this point.
