I'm not sure if there's just a setting I need to change, or if it's a bug, but oceans in LOD chunks have a sort of "light-grid" to them, and farther away they have gaps in between chunks. The gaps only seem to happen with the terrain generator mods I'm using, Terrralith and Tectonic, both together and with only one at a time, but the "light-grid" still remains even with only DH. Either way this only applies to oceans, normal chunks are fine.
The pictures are on MC 1.20.1, Forge 47.2.0, with DH 2.0.1-a-1.20.1 and Terralith 1.20.4_v2.4.11 .
Figured I'd just make a help me post first unless it turns out to be a bug.
