Trying to add distant horizons to a modpack.
Cant load server

new LODs are not loading despite chunks being generated.

Using chunky but just getting generations that look like this

Distant Horizons Renderer has encountered an exception! FloatBuffer
I played with this for the past week and didn't have any problems until yesterday when I had my first error, which was fine I just deleted the toml file and started playing again. but today I got an error that said something along the lines of "DH2.0 not found, but Fabric claims its there." I preceded to update to a newer version of Iris, the LODs weren't building so I deleted Iris and reverted back to the file link above. Ever since then I've been getting the error in the picture every time I go to turn off DH in the options screen....

Multiplayer: LODs carry across server maps

shaders / rendering on LOD chunks is weird and fuzzy

would u be willing to make a 1.12 version?
How do I properly install nightly builds?
is it possible to run it on a server with any specific version?
Is there a way to use Distant Horizons for 1.20.5/1.20.6 (fabric)?
Doesn't load saved chunks (Fabric 1.20.1, server, multiplayer)
