A similar issue has already been closed; the solution of using Sodium with Indium doesn't work for me. Tested with Fabric API, Sodium and Indium only.
Mod version: 1.12.0
Fabric API version: 0.58.0
Sodium 0.4.1+build 15
Indium 1.0.7

I'll take a look into this and see what's happening. Thanks for reporting it, and apologies for the slow reply!

This seems to be something to do with how Sodium has changed the way world chunks fetch BlockEntities.
I'm not sure if this is a problem on my end, or a problem on theirs. Further investigation pending.

Just an update that this seems to be a Sodium problem, which the CaffeineMC team don't seem to be addressing, so I'm not sure how to proceed here.

Hi, just to let you know; I think I've managed to fix this!
I'll be releasing a new version with some pretty big fixes in general pretty soon, so keep an eye out for that.
