Skypetal Visual Error

[Rinehart]

Since yesterday, I noticed this visual error

 

 

As you can see, the ground textures don't seem to be working. I've tried tweaking with the visual settings, as well as relogging and restarting.  I'm wondering if somehow, my files got corrupted but idk which file to fix nor do I want to simply redownload.  It is a rather minor error imo since I've only noticed it in the Skypetal Plains area... though it doesn't seem like anyone else was having the same issue.
