Kaiba the Revenge - Indestructible Relinquished (Yu-Gi-Oh! Power of Chaos) [Bug]

After dragging on till the last card, Kaiba gives up doing over 15,000 damage too himself in one turn! In this duel I come across a bug with relinquish leaving it nearly indestructible for as long as no cards are in the leftmost spell/trap card zone when it is attacked nor a card destroyed in that spot. Some further testing after this video I was able to see cards can be played in that first spell/trap slot as I did often here, but if they are destroyed, it fixes the bug.
