Bugs fixed:
Right clicking with tipped arrows would fill up cauldron and give empty bottle
Another quick update on the development front, this plugin version is temporary, right now cauldron values are stored in the plugin folder, this will soon change. Changing this should improve the stability of this plugin (which has not been an issue on my end so far but may happen in very specific situations).
This change will come out soon but for now, enjoy this plugin for version 1.20.1!
