Diamond armor got deleted by iron armor when trying to equip.
I expected it to exchange the two different armors.
It deleted the armor that I was wearing.
Steps to Reproduce:
1. Equip with diamond armor (or anyting)
2. Get a different kind of armor and equip it without taking off the other armor.
3. The original armor will be deleted
Sorry about this, for some reason it seems I always removed the armor part before putting on a new, like in a furnace (or I didn't see the missing armor, cause I have a gazillion!).
