2. Right click with the bucket of water on the Petal Apothecary

What I expected to happen:
Fill the Petal Apothecary with water

What happened instead:
The game crashes

forge made an incompatible change
workaround: downgrade to 33.0.20- until this is fixed

I have the same problem with just right clicking the petal apothecary with an item in general. Throwing items in works though.

fixed in 406
