False Positives of desert wells locations:

These are all on 1.20 pre-release 5. I have a feeling it is due to terrain/water/cave.

The README specifies that jungle temples and desert temples have inaccurate results from time to time in 1.18+. I wonder if the same issue is the same one affecting desert wells.

Chunkbase lists desert wells as "likely desert well".

There are also false negatives. Seed 244465802287175713 has a desert well at -7504 -2541, but it doesn't show up on Cubiomes. (1.20.1)
