LOD's randomly turn off

Like the title says, LOD's randomly turn off after 1-10 minutes. I'm on 2.2.1-a 1.20.1 forge, I do have Alex caves installed, but I have biome ambient light / coloring off. I'm playing with Complementary unbound & euphoria patches

Solution

Using this one, they stopped turning off and randomly refreshing, they load a bit faster too
