None of the chunks load when I enter the nether, I could see the particles from the nether portal, but that's it. Some of the blocks were loaded enough so I could walk on them, but none of them were rendering. At some point I fell off the partially loaded blocks and started falling. from there I waited like 10 minutes, but I just kept falling (my y coord was well under -10000) so I gave up and tried to save and quit. That got stuck on "Saving World" for a long time, and I ended up just force-closing the game. It didn't crash, so there's not a crash report at least that I could find. Here's the log: https://mclo.gs/Yxs2krP

Update: tried it again and mostly the same thing happened except a few seconds after going through the portal the screen just turned gray, and nothing happened.

Seems to be fixed in newer versions
