It’s seems there’s a particular spot on the stairs of Horn of Magus final event where rats can get stuck and try to phase out of reality. Not a single rat lived long enough to get free of it.
Doesn’t seem to affect chaos units.

- Play Horn of Magnus and get to the final event.
- Stand in the spot where everyone usually stands aka in front of the big window.
- Watch the stairs on your left.
Here are some videos of various rats getting caught:
