For some reason the Gurty Mobs are spawning in the end for me, which from what I can tell isn't where they're supposed to spawn.
I'm assuming it's caused by a incompatibility between this mod and Outer End, seeing as the Gurtys seem to like spawning around biomes added by that mod. Here is some images for proof/example.

Oh and if your wondering about the random cornflowers around the end, I believe that may be a bug with another mod. If I find any evidence that could link this mod with that glitch, then I'll let you know as soon as I can.

Thanks for your time. If you have concerns, feel free to let me know.

I'm working on this mod now. The corn flowers are Gurty nests. They are supposed to be cleaned up when Gurty's respawn or are killed.
They are going to be replaced with a nest that you can right-click or break for loot eventually.

Gurty's should NOT spawn in the End. They are supposed to have water within 7 meters of their spawn spot. I'll fix this within the next few days even if I have to remove the new snakes temporarily.

I think I fixed this back then but I'm not sure why I didn't close the issue. Please let me know if I did not.
However, changes to the biome tags broke it again so I fixed it in 1.20-1.20.1.
I'll be checking 1.19.4 and 1.18.2 versions to confirm they look fixed and then update this issue with what I see.

Please let me know if you are still seeing it.
I'll close this in a week if I haven't heard anything.

from what I can tell it seems like your fixed it back in the relevant version, but I'll do a lil more looking and tell you if I find a anomaly.

Yeah, I think the issue is fixed. Thanks for you work!
