Elevator blocked on cleared gauntlet floor

[That one stingray]

I am trying to get the gauntlet diamond badge, and this is the furthest i've been, level 27! I will be very very sad if I cannot continue this save.

Essentially, I have killed all enemies on the floor, and the exit elevator is unable to be accessed, showing the "GATEKEEPER" particle effect. However, there are obviously no gatekeepers alive, because nothing is alive, because I killed them all. I'm guessing there's some edge case where GATEKEEPER enemies dying in certain ways (UNSTABLE chain explosion? bleed? Friendly fire?) are not removing the block on the elevator. If this could be fixed or if anybody knows some way that I can edit the save to unbug the elevator, I would greatly appreciate it

I figured it out, turns out that hacked GATEKEEPERS still block the elevator, I didn't even realise there was something hacked on the floor. Kind of my bad but also kind of not because I think when you own a robotic enemy it should disable effects that only disrupt the player
