Hi,

it seems there's some sort of incompatibility between StackableItems and CraftingPlus that prevents shift-clicking items in a Crafting PlusBench from working as intended, causing those items to be transferred (you could say duplicated - or given) instead of used up & crafted like they should (similar to the way it works at a furnace, crafting table etc). CraftingPlus re-uses the chest layout to automatically offer items that could otherwise be crafted at a standard crafting table, based on items the player carries in the inventory. It then crafts items when clicked (or shift-clicked) and uses up corresponding needed items from the inventory.
I may be wrong, but I suppose, that there's a priority issue of some kind. StackableItems doesn't seem to be aware that a CraftingPlusBench is a CPB and not a chest - thus, in a chest layout, it would be better if StackableItems would somehow respect (or inherit) the shift-click functionality added by CraftingPlus (instead of overriding it).
I hope that this can be resolved somehow.

Also, you may want to see comments #108 to #111 over at the C+ page.

Cheers. Just letting you know this issue is still happening (with StackableItems 0.9.1 and CraftingPlus 6.2).

Thanks for letting me know, I might have to hook directly into the plugin for it to work unfortunately, but I'll see what I can do.

Unfortunately, I was not very active with handling these tickets and it would seem it is now too late to handle CraftingPlus as it is no longer being maintained, but I do have an idea that I will try to implement to handle future plugins with different inventory types.
