A new bug tonight:
When zoning into Vex Thal clicking the disc for some, but not all, of raid gave the message zoning into Vex Thal but...they ended up under world in Umbral. This happened to me and another guildy. The other guildy once got the message that VT was not ready to receive visitors or something. The zone seemed rather choppy tonight.
This is however the first time we've had 6 groups in there...maybe we were pushing zone limits somehow, IDK. We eventually dropped one group and got 5 groups in. It seemed like it could be a zone capacity issue as those kicked underworld were always the last ones in.
