I've been experimenting in 1.17.1 (Java), particularly with the new dripstone. However, I've been unable to figure out a way to empty filled cauldrons. At first, I thought it was a problem of aiming the dispenser correctly, but I've now got a setup where it is directly above the cauldron and aiming downwards.
Can I expect this to work? Or will it just dump the empty bucket into the lava cauldron?
