Describe the bug
After enabling the Official ROTN tweaks resource pack the game started throwing errors in the chat. I started finding random transparent blocks in the world. As you can see in the logs, seemingly unrelated blocks are affected. I was not able to reproduce the bug without the texture pack enabled. Disabling it fixes the issue until enabled again.

To Reproduce
Steps to reproduce the behaviour:

Enable the rotn texture packs and travel. Certain locations seem to be unaffected - not sure which or why, but running into the error doesn't require travelling more than 100 blocks according to my testing

The resource pack can be either enabled alone or with the other ones below it - the issue persists.

Expected behaviour

Blocks should render normally

Additional context

Log file: http://www.mediafire.com/file/e1map58cp0wqx4i/latest.log

I can't reproduce the bug on Windows - it seems like it's exclusive to Linux, along with other issues like music not working

eh? this is the end of the file - did you close your game before sending the log? (it only writes to log after game stop iirc)

Nevermind, you can probably close the issue.

I forgot optifine installs automatically in this version and installed in manually myself out of habit. As you can see in the logs, I am running 2 versions of optifine at once. Surprise, surprise, removing one of them fixes the issue - after 10 minutes of testing, I was not able to reproduce it. It's probably not related to the os after all.

To answer your question - I did in fact not close my game before sending the log. Sorry about that.
