you literally released a public beta of 1.18...
Yes
You have to be away at least 24 blocks for mobs to spawn
Nope just got my really broken diamond pickaxe with mending
That happened to me i placed lava in a water source and it turned to obsidian and it had the light level same as a lava source
The same problem on switch
Same on Switch but i get lags only if i have shulkerbox with items in inventory. I recommend to disable menu animations option.
ok ur right and yes I checked this is also in older version like 1.17.1
