Interrupted staircase bug on Deimos

[XK_ZC]

A small downward staircase in the Deimos map will cause a black screen every time you pass it (similar to the black channel and teleportation return after falling from the edge of the map). You can only pass it normally by crossing it from the air. It just happened that the new version was updated, and every time it was interrupted, the frequency went black, which was a bit uncomfortable. I hope it can be fixed. Thank you
