An hour into Duviri and we get to another Assassination, we were going well so far, but as we got to the end of the Jackal's second stage, it didn't move to another arena, then got stuck in an endless loop where we'd down it and mercy it, but it would just get up in the same spot and continue, never progressing, endlessly. Meaning we had to end our run by leaving prematurely.
Additional info:
I was the host, there were no migrations
We had a Hydroid, Voruna and a Revenant
