Thanks for flagging this for us. I gave it a shot with a level 14 Cleric but didn't run into the same problem. Has this popped up in multiple sessions? Just wondering if it could be related to server load or a specific event.
Any more insights help!
Cheers,
Mark
MAB poked me about following up on this, hence the threadromancy.
I'm actually a Fallen Cleric right now so I can't do fresh tests, but it did happen a few times. If/when Talis gets her powers back, I'll keep an eye out for further instances.
Edit:
This hasn't repeated itself. Hopefully it is resolved.
