I've encountered a very unusual problem when trying to make Tree Poison with the Cauldron.
When I click the "make more" button for Diabolic Acid, it will instead bring up the screen for making Abbasidose. If I make Abbasidose from this screen, it will give me the specified number of Abbasidose, AND an equal number of Diabolic Acid, for only the cost of the Abbasidose. Pictured below:

I can still make just the Diabolic if I start from the Test Tube menu instead of the Cauldron; it appears to be only the Cauldron menu that is glitched.
