Looks like it's still not finding the command correctly.

Ideally, I'd want to be searching for the following:

! <Then the command from $2>:# <The $chan from twitch> :

i.e.

Code
 !testing:#eggfriedcheese: 


So that it's looking for that command in their channel, and then once that's found, it deletes.
