World corruption caused by slab placement #181
Description
My world gets corrupted if I make this shape
You can make it, and you can even save and exit. If you saved in the same chunk and reload your save, you will enter a world with nothing but the skybox rendered in and can fall forever. If you save in a different chunk and then get near it, the chunk won't load, and your character will glitch out. (In my case, once using the elytra, I'm unable to walk again).
After some testing, it appears it's when the 3rd slab across is placed. (again the error occurs after saving, exiting, then reloading in)
I can provide more info if needed.
