Description:
I updated my Minecraft Fabric Server from 1.21.1 to 1.21.3 and every time I start It a lot of warnings appears on the console.
I checked if there's some anomalies in game but everything seems to work just fine.
I'm not completely sure if this depends only from Lithium or Fabric too.

Technical Details (all mods used on the Server linked here):
Fabric Loader: 0.16.9
Fabric API: 0.108.0+1.21.3
Lithium: 0.14.1-snapshot+mc1.21.3-build.89
Java Version: 21

Changed the warnings to info level

The warnings should probably be INFO level instead. In the latest release some optimizations are disabled by default, because they have issues.

Okey, then It's good to know that there's nothing to worry about.
If Lithium get updated and those warnings will disappear then I will close this issue post or you can close it too, thank you for the answer.
