Confirmed bug for the base game
oh lol its a baby zombie villager riding a chicken. sorry for confusion
Also I have to start recording with the F3 screen off because the recording software doesn't allow it
Maybe chunk borders have something to do with it?
I have the same issue with another world.
This is an intended feature. Sugar Cane has water-displacing properties, and can be placed on sand/dirt as long as there's an adjacent water source block on the same y level as the sand/dirt.
Certain squid farms use this feature to obtain ink sacs, and it can be used to create underwater paths too.
Mining gold blocks, gold ores, gilded blackstone will anger the Piglins. Also, opening chests or breaking them will anger them too.
The software I used to read the NBT data of the world is NBTExplorer. It is almost certainly working as intended
