Im making a custom map at the moment, and have been using worldedit to help me. However, i have accidentally set a brush to turn an area into torches (pics below) whenever i finish a stack. I was wondering if someone who has used worldedit could tell me what ive done wrong, and how to fix it. thanks!

I'm very confused, is this on another server?

If used //rollback it may got it back

this is in single player. I think ive sorted it.

dont use torches in any WE...it will destroy you XD
