In the video you can see one drone stuck behind that glass wall. After I recorded that clip, I found the second stuck behind one of the plants left of the drone in the clip. Those 2 weren't that bad, because I found them and I could kill them.
However, the third enemy (probably also a drone) is either stuck somewhere in the ceiling or beneath the floor. I think he got stuck in the ceiling and isn't able to come out of his hole (the on you see at the end of the clip) because of that. I can't continue my run now, because I can't kill it.
edit: I'm adding a counter to keep track of how many times this specific bug has ended my run.
Counter: 12
