Couldn't get credit for completing Mage Tower?

Hey all, I think my Mage Tower is bugged.

I’ve killed the boss as Ret Paladin and as Feral Druid, but I didn’t get completion credit (no clear completion/achievement/unlock afterwards). Boss dies, dialogue finishes… and then it just stalls. No button to press, no completion, no achievement—nothing. I waited forever and the only way out was clicking ‘Leave Instance’.”

Has anyone run into this recently?

• Is there a known issue with Mage Tower credit right now?
• Is there a specific requirement I might be missing (scenario version, timewalking active, etc.)?

Any advice or workaround would be appreciated. If this is a confirmed bug, I’m happy to report it—just want to make sure I’m not doing something dumb first.
