Gauntlet room for Sanctum not ending

I have tested this a few times and on the first and second floors the gauntlet rooms with guardians spawning constantly and the beam trap in the middle. A guardian can be blocked from spawning by placing totems on their dark spawn point and if that happens, after the gauntlet ends the exit door will not open.

yeah, this just ended my no hit run and i quit the league. lol.
