Now occurs again in 1.19, 1.19.1 Pre-release 2
Same issue here.
Can confirm in 22w17a.
Slabs work completely fine. Cannot confirm. Plus, updates to the game are free, you do not pay for it monthly. The game works fine and always has, please do actual research instead of spreading lies. Plus, since this is Java Edition, you can freely go back to whatever version you want without it updating via the launcher/ There is no chance that you will get them to stop updating the game.
Can confirm in 1.18.2.
Can confirm for 21w43a, 21w44a
Cannot confirm in 21w43a
Can confirm in 21w16a.
Can confirm with void and blindness in 21w08a and 21w08b
Can confirm in 21w08b with both blindness and The Void.
Confirmed in 21w07a with both blindness and The Void.
Confirmed in 20w48a in End Void without blindness, as I reported in MC-206739
Found this since this was placed under "Duplicated By."
Can also confirm.
Can confirm in 20w48a AND 1.16.4.
Can reproduce, see newer attachment.
Edit:
Geode cavity seems to have spawned close by underground but has an unusually thick layer of Calcite and Amythest leading to the part shown in the image. rest of the geode spawns as usual.
