Abyss Not Completing

https://www.xbox.com/play/media/hBgKbHWW5B

This has happened on 3 different maps today- 1 abyss in the map will not proc the 2nd wave with rare monsters to complete it. 0 monster left in map, but it still shows active.

Measly complaint, I'm sure- but that last one that may lead to the depths is where my money is at 😅
