Ground occasionally disappears.

As the title (hopefully?) clearly states, occasionally, I’m fairly sure due to an exploit of some sort coloring the world, the world just stops drawing entirely and looks like the “void” that you sometimes see in badly made maps. (The infinitely redrawing kind)

Some (hopefully) screenshots.

(Incase they are broken)

EDIT- This is on my server I get off of, so I can’t provide any specs or anything.

That’s weird. The server I was on had something exactly like this. The error in console was:

Material nature/grassfloor002a does not support vertex format used by the mesh (maybe missing fields or mismatched vertex compression?), mesh will not be rendered. Grab a programmer!

Do you have any errors in console? Also try updating video drivers.

Actually. It happened to everyone that was on the server. Not just me.
