I cannot reproduce this. Tried on an alt as well with a moderator rank. I'll need more information / screenshot. Perhaps it's been fixed since your report, since I'm getting back to you quite late. Let me know.
pet selector is working but it gives this error message, it's almost like the pet access wasn't added to my account
@andrewkm I tried /pet selector on an alt that doesnt have the pet features and it gave a similar error message. Seems like access to the pet didn't get added to my account. So maybe it's not a bug as much as a feature not getting added xD
@xHigh420x looks like the issue was the actual pet polarbear not being in your account. Should now be fixed. Please confirm.
