Hourglass Trial Spawns Almost No Monsters

I run a lot of Sekhemas, and I don't think it is by design that the Hourglass Trial room sometimes spawns almost no monsters. This requires the player to spend almost the entire clock duration in the room.

I cannot pin down whether it happens on a certain floor or Hourglass room layout; but it happens about one in every 5 Hourglass trials.

I've had the same issue, its with like half of the layouts. People say, "Gotta run around and kill stuff." like I don't already know that. Half give rare mobs, the other half gives only white mobs so you have to be there the entire time.

Another day, another bugged hourglass room on floor 2.
