Relics of the Privateers seems to create client side chunk errors

Build: 418100
Summary:
Flying around Relics of the Privateers, I noticed chunk errors. Confirmed I was not in no-clip mode, couldn't step on the blocks and fell straight through. Could interract with the blocks in the walls. Reloading would fill in the chunk. Did not notice this on any other worlds.
Impact:
Critical bug that renders areas invisible that could be required for the map to work.
Repro Steps:
1.Fly around the world and they appear
Observed Results: empty chunks that you can go into, and create in, but are kinda sorta not there?
Expected Results: The regular build
