Quote from Farmbuyer/suf -> Enabled Units -> Raid
There's a bug in that initially joining a raid, or doing a /reload, will quite often cause one of the raid's subgroups to not display at all. Most reliable workaround is /suf and then on the general tab, toggle "lock frames" off and back on.
Thanks so much! I feel silly not even seeing the Enabled Units section. it works now. :)
