Black LoD chunk persisting through LoDs

I'm having a visual glitch where a black rectangle(color presumably from block) stretches all the way down from where I've built and it has somehow persisted through me deleting the save folder for LoDs and making a new one. it's on a multiplayer world with 130 mods. Log doesn't show any errors nor is there any ingame. here's some pics to maybe show it better visually.
