I tried searching for a similar problem, but could only find old ones, like: MC-184740
This is basically my exact issue, I wanted to test rates for 1.17 vs 1.18 because i heard 1.18 spawn rates are bad. (Formula for sub-0 Y-level spawn rates should make < 0 more common, leaving existing spawn rates unaffected)
Anyway so I loaded my world in 21w41a, and my witch farm was full of spiders and no witches.
Expected behavior: Only witches should spawn within the (now demolished) structure.
Observed behavior: 'all' mobs spawn in the chamber, virtually no witches.
World created in: 1.17.1, chunk generated in 1.17.1
Chunk details: see screenshot
