We’re in the Abyssal Hordes and have made it through 5 waves, but the game won’t let us progress to the final wave. When we try to open the door to the last wave, a message comes up that says “You must defeat more waves.” There aren’t any more! All enemies have been defeated. We tried portaling out and back in to no avail. Time and aether wasted 
Has anyone else encountered this issue?
Having the same issue
Having the same on xbox with couch co-op. 3 out of 4 T7 runs hung at “slay remaining enemies” on a middle wave, with everything already dead. I haven’t seen it solo yet. I tried TPing out and back, having one member leave party, but i found no way to force progression.
Same thing with multiple Xbox couch co-op glitches.
Various T-levels at various waves all the way from wave four (maybe earlier) to the door not opening.
Very frustrating.
Not fixed after a month
Same here. Needs to be fixed!
