Lithium Cached BlockState Flags are disabled!

Lithium generates information about each block state at startup and uses the information to speed up various parts of the game. But since this information is dependent on block tags, which can be changed by data packs, the optimization is incorrectly using the outdated block tag information. For this reason the optimization is disabled by default until this is fixed.

The affected setting is mixin.util.block_tracking

so its normal to have it like that?

Yes, currently everyone has that
