Hello.
You're overwriting some Blizzard defined globals, particularly CHAT as you define in line 253 of CrossGambling.lua. This particularly overwrite messes with RCLootCouncil and probably a lot of other addons as well.

In general it's bad to ever write anything in the global space (of which you do alot), but touching Blizzard globals is really a bug no-no. You can use tools such as Globe! or Mik's FindGlobals script.
