(flashes vid)

this is the code

func (h *InventoryHandler) HandlePlace(ctx *event.Context, slot int, it item.Stack) {
    enchant, ok := ce.FromBook(it)
    if !ok {
        return
    }

    targetItem, err := h.p.Inventory().Item(slot)
    if targetItem.Empty() || err != nil || !enchant.CompatibleWithItem(targetItem.Item()) {
        return
    }
    if err := h.p.Inventory().SetItem(slot, ce.ApplyEnchant(targetItem, enchant.Type(), enchant.Level())); err == nil {
        ctx.Cancel()
        time.AfterFunc(time.Millisecond*50, func() {
            h.p.Inventory().RemoveItem(it)
        })
    }
}

if it helps this is whats showing in the console

Directly after the book is placed on the item it sends this: DEBU[0047] failed processing packet from (R53D): ItemStackRequest: error resolving item stack request: *protocol.SwapStackRequestAction: action was cancelled The console thing shown above happens when you try and drop the item after using the book on it.
