I am not the original poster but a mutual friend of Kitkatarine and I ran into the same glitch while they were building in their player house.  One of the floors proceeded to go pitch black.
Relogging fixed it once, however upon exiting and re-entering said floor the glitch reoccurred. 

Key & Slot: Effervescent.slot3
Date and time: 7/8/2021 5:07PM PDT
How to recreate: Walk into an extra level in a player house

Addendum: They are able to relog and enter the room without issue. However leaving and returning to it will cause the room to glitch once more.  This has re-occured at around 5:30 PDT.
