Hello,
my game just crashed for no reason. After the crash, the world is corrupted and cannot be played (crashes). It has to do something with Create.
Crash log here: https://mcpaste.io/895f801011732ddd
Modlist here: https://mcpaste.io/f3db6d24e00a1746

Please fix this issue.
Thanks

Edit: Just so you know, I was just loading new chunks and this happend.

It is an issue with FML v35.1.37.
Downgrade to 35.1.36 and the issue will be resolved.

Ok, thanks, I will try that.

I would like to comment that I also had this issue and discovered the reason was due to Optifine 1.16.4.
I actually discovered that Optifine 1.16.5 actually works on Forge 1.16.4 and does not cause this problem anymore.
I had to use the latest version of forge, as listed above, because some mods I had required that specific version, that is how I found this "solution". I simply just use Optifine 1.16.5 instead of 1.16.4 on Forge v35.1.37.
I also just happened to notice that in your crash log, you have Optifine 1.16.4 installed, so I thought this was a relevant comment to make.

I can confirm this works, I had the same issue, downgraded to that version of forge, and now I can load my world. I am really disappointed though that the forge config no longer offers the option to remove erroring entities like it did few MC versions past. If this downgrade of forge didn't fix the problem, it looks like I'd have to resort to using MCedit. (also the only thing I had in my world was the water wheel that was erroring)

Thank You, Optifine 1.16.5 worked.
