What you were expecting to happen, and what actually happened:
I was fighting first room of the City of Thieves delve. The enemy died, I won, so I was expecting rewards. Instead I get error CLIFFY-ERRNU9OIBF. The only option presented was to restart the game. Doing so resulted as a loss for the delve.
How often does this happen? When did it begin happening?
This is the first time I have ever received a Cliffy error.
Steps to make it happen again
Since this is the first time I had this happen, I do not know how to reproduce it. I won the fight in the delve when the error popped up.
I will be submitting a support ticket as well as this incorrectly resulted as a loss, and delve runs are limited.
