No rares spawning in Sekhema hourglass trial

Bug Report ID: #2673333777

- In the Sekhema Hourglass Trial no rares spawn at all or they stop spawning after killing the initial ones
- This has occurred multiples times today, across different runs and different floors
- In each case I ran around all corners to make sure there is no burrowed devourers shenanigans
- I am constantly killing the white mobs that are spawning

Not sure if valuable, but here are some additional reports from other occurences:
- Bug Report ID: #4099885891 (happened in the next hourglass room after the one at the top of the post)
- Bug Report ID: #3409605229

I wanted to +1 this post. I've had this issue happening in several sekhema hourglass trials as well. It seems to happen most in floor 2 sekhema hourglasses, and there will be anywhere from 0 to 3 rares spawning at most. After the 3rd rare (if it even spawns at all), other mobs continue to spawn but no rares spawn any longer so we have to just wait out the timer normally.
