[Bug]: no dragon nest or caves spawning in

[bunyx]

What happened?

I started a modded Minecraft world and at first a lot of nest were spawning. now I can't seem to find any new once and I traveled a lot! And digged a lot but no caves.

When I first started there where 2/3 nests but now I can't find a single new one even if I explore new places

I tries change the settings in the config folder but even then not a single one spawns in. (I went into spactator in a new world)

I tried the dragon seeker and eye mods and still can't find dragons. I also removed the other mods and still nothing. other structures are spawning in.

it really bumps me cause the searching is one of the most fun things

I really hope anyone can fix it for me
