Lose to Exiled Mage, Lose the Echo

I dont know if this a bug or not but figured I’d mention it here
If you lose to the Exiled Mage before completing the echo requirements in the Monolith you will lose the echo.
If you wait until you complete the echo requirements to challenge the Exiled Mage you will still get credit for the echo even if you lose to the Exiled Mage.
