Another snapshot is now going out. This time around, we fixed quite a few bugs, and we also introduced some changes to some Caves & Cliffs features, and additionally, we added some extra context for the narrator.

Changes in 21w20a

Actually made geodes rarer this time
GUI narration now includes position and usage of hovered or focused element
Tilling rooted dirt with a hoe will now convert it into dirt, and pop out a hanging roots item
Axolotls will now only play dead when in water
Llamas no longer spit at players in peaceful mode
