• Geolosys:5.1.4
• Patchouli-1.16.4-50

What happens:

(Sorry. I'm not good at English. I used Google translate.)
A huge number of lakes are generated when I use this mod. It occurs mainly in plains and forests, regardless of seed.

Agreed--and not just plains for me; savannahs and tundras are also prone to this. Great mod otherwise--best of luck figuring it out if it hasn't already been resolved!

Same problem

Woah, I assume you guys have tested the exact same seed without geolosys as well to see that those lakes don't spawn? This is wild
