Hello!

I've been having a weird glitch happening on a custom modpack on a multiplayer server.
I'm using the latest 1.20.1 versions of all the mods but it's been happening for a while even on previous versions of the mod.
Whenever I load in some create factories and then fly away I can see the blocks still remaining in the unloaded chunks.
Only happens when I have the shaders enabled and if I remove the mod, the problem goes away even with shaders.

There's a lot of mods in the modpack and I've tried disabling some of them but still can't figure it out.
Any ideas what could be causing this? Thanks for any suggestions.

Have you tried checking if the issue still occurs when not using the shaderpack?
