I get a "Select Databroker Plugin" error on US alliance version realm Tichondrius. ( every single character of 6 having exact same issue on this realm... all other realms i don't have any issues) I change zero settings and move to different server and may bagnon work perfectly...

Bagnon works perfectly on all my other realms that my characters are on except this realm.

I'm not sure why it isn't working but it sure seems to be realm related, please look into it.
