We’ve received reports of some game instability occurring on the PTR, most notably when changing zones or during the Siegecrafter Blackfuse fight in the Siege of Orgrimmar raid. We are currently investigating the issue.
We’ll have another Siege of Orgrimmar raid playtest soon, for additional testing.
I understand getting the ptr stable is top priority, but could you please take a look at nameplates on ptr? base nameplates are not working on enemies for most people. My friendly nameplates work, but they can’t be turned off, and enemy nameplates are not working.
Fwiw I have submitted a bug report, but it’s exceptionally frustrating not having access to nameplates.
