Describe the Issue

I am using a Bukkit and Forge mixed Server core named Arclight.
I found an item duplicate bug with the Bukkit plugin QuickShop.

When I use the "preview sale item" feature in QuickShop, it will show me a GUI with some item in Shop, that should not be moveable, but when I pressed Delete (The default Key of delete item in TrashSlot), the item which shouldn't be moveable was transferred to the trash slot in GUI.
Then close the GUI and open my backpack, the item in the trash slot can click and move to my backpack now.

So I think this will cause duplicate items.

The author of Arclight said, it was caused by TrashSlot Mod, this mod use their method to move item between gui.
See IzzelAliz/Arclight#505 for more information.

Do you use any performance-enhancing mods (e.g. OptiFine)?

No

TrashSlot is not compatible with Bukkit plugins. Since server-side plugins simulate these slots without making them actually "unpickupable", there is no way for TrashSlot to know whether it's a real slot or a fake one.
