The bank script does not have a check for free slots in the player's container. When withdrawing amounts that occupy more slots, items are thrown to the floor.

Apparently there is no specific function in TFS for this, how could this check be done before handing over the gold to the player?

Unfortunately it didn't work. The free slots were filled, but the rest went to the ground.

I didn't check the rest of the code, just updated /changed the canReceiveMoney function.

amount 59 = 1 slot required
amount 22222 = 3 slots required
amount 1234567 = 4 slots required

LUA: 
local function canReceiveMoney(player, amount)
    local backpack = player:getSlotItem(CONST_SLOT_BACKPACK)
    if not backpack then
        return false, "You don't have a backpack equipped."
    end
  
    -- Calculate total weight
    local crystal = math.floor(amount / 10000)
    local remainingAfterCrystal = amount % 10000
  
    local platinum = math.floor(remainingAfterCrystal / 100)
    local remainingAfterPlatinum = remainingAfterCrystal % 100
  
    local gold = remainingAfterPlatinum -- not required but added to make it more clear
  
    local crystalWeight = crystal * ItemType(2160):getWeight()
    local platinumWeight = platinum * ItemType(2152):getWeight()
    local goldWeight = gold * ItemType(2148):getWeight()
  
    local totalMoneyWeight = crystalWeight + platinumWeight + goldWeight
  
    if player:getFreeCapacity() < totalMoneyWeight then
        return false, "The money would be too heavy for you to carry."
    end
  
    -- Calculate total slots required
    local crystalSlots = math.ceil(crystal / 100)
    local platinumSlots = math.ceil(platinum / 100)
    local goldSlots = math.ceil(gold / 100)
  
    local totalSlotsRequired = crystalSlots + platinumSlots + goldSlots
    local availableSlots = backpack:getEmptySlots(true)
  
    if totalSlotsRequired > availableSlots then
