I noticed on a server I play on, my mob farms broke. I went into a singleplayer world on 1.16.1, and recreated the creeper farm. When I noticed creepers were not spawning, I removed all the items in the room (carpets and trapdoor to make creepers spawn) and noticed mobs were not spawning anyways.

Thank you for your report!
However, this issue is Invalid.
Your game, launcher and/or server is modified.
If you can reproduce the issue in a vanilla environment, please create a new ticket.
Any non-standard client/server/launcher build needs to be taken up with the appropriate team, not Mojang Studios or the Bugtracker.
Any plugin or resource pack issues need to be addressed to the creator of the plugin or resource pack.
If you have problems on large servers, such as The Hive and Hypixel, please contact them first as they run extensively modified server software.
