The code below was copied from transferFrom(), so any function calling _transfer() needs to confirm that to is capable of receiving NFTs. loanFacilitatorTransfer() calls _transfer() without completing this check, which can lead to the loss of NFTs. Checking if the address is zero or not is not sufficient; it needs the other checks in safeTransferFrom().
