Ghost monolith randomly showed up

Hi, so I've been playing on this server that doesnt have serverside DH but I have it on clientside. for some reason a giant glitched chunk showed up right by my house. It's mostly visible from a distance, but it fades out like an LOD when I get close to it, so I'm assuming its a DH issue. Nobody else on the server can see it and it was not there previously. Logging/restarting game does not fix it. What should I do?
