This particularly bothersome bug happened when I dropped group, but OQ would not remove me from that group and locked me out of other groups.  Reload, and restart of the game did nothing:

Still giving Lua Errors and still not able to get out of the group:

please update to 1.8.3a then disable all addons except oQueue and log in.  this will help eliminate the possibility of another addon conflicting.
