Can't queue for a BG unless I disable dominos.

Have you tried with just Dominos enabled?

It was the only addon I had. Everything else is default blizz. I'll try it again tonight, it could have been user error with something else and I really like the simplicity of dominos.

One thing to also doublecheck is to see if you get the issue with just Dominos, and Dominos_Config (and no other Dominos* addons)

It works now so I don't know. User error.
