The bug
You are unable to use waterlogged block to fill empty glass bottles. This affects both the player and dispensers. It doesn’t even work when aiming directly at the waterlogged block, relating to MCPE-56024.
To reproduce this with the player:
Place a slab
Waterlogg it
Try to fill a bottle using the waterlogged slab
❌ It will not work
To reproduce with dispensers:
Place a dispenser facing into a waterlogged block
Fill it with a glass bottle
Power it
❌ The dispenser drops the bottle instead of filling it.
Expected result: Players and dispensers are also able to fill bottles using waterlogged blocks.
For hand animation playing when trying to fill the glass bottle see MCPE-60824.
Now, since version 1.19.10.20, it is generally impossible to fill a bottle by aiming at a block underwater.*Dispensers work the old way.fixed
