If you shift right click a double chest with the flower pouch with flowers in it, it puts the flowers into the chest (as expected), but then shows a GUI for a single chest.

This is minecraft's fault, IIRC. Double chests are a total hack, and supporting them is a waste of time IMO

No, this is fixable, I do have double chest detection code.

Sorry, I must have been thinking of Azanor

@Vazkii just cause its fix-able doesnt change the fact that double chests are a total hack! 😜
