Moving items and unequipping gear not reliable

[ownedbynico]

Hey,
so I implemented a banking feature in my addon. But it's not really reliable since sometimes there are 1 or 2 items that appear to be stuck.
I added a 200ms delay between Item move requests. Is that too little or is my basic thought wrong?

This is my function to move items which Im calling in a loop.

function MoveItem(sourceBag, sourceSlot, destBag)
	if not DoesBagHaveSpaceFor(destBag, sourceBag, sourceSlot) then
		return false
	end
	local destSlot = FindFirstEmptySlotInBag(destBag)
	if not destSlot then
		return false
	end
	CallSecureProtected("RequestMoveItem", sourceBag, sourceSlot, destBag, destSlot, 1)
	return true
end

Thanks for any help in advance
