Bug cauldrons not working

[JakL]

The crafting GUI does not appear when i right click the cauldron.
I haven't crafted anything in quite awhile so I don't know when it stopped working.

Double check what kind of wood you are using to light the fire beneath it, a lot of the newer wood types don't work properly. Stick with the classic oak or birch and see if that fixes the issue

also make sure the cauldron is filled with water.
