Summary:
If you upgrade a world from before 1.9, items held in hand or worn in armor slots by mobs and armor stands get shifted and deleted.
Items from the feet slot are moved into the mainhand
Items from the legs slot are moved into the offhand
Items from the mainhand slot are moved into the feet slot
Items from the chest and head slot are deleted
Steps to reproduce:
Or you can just upgrade this world:
Start version 1.8.9.
/summon ArmorStand ~ ~ ~ {ShowArms:1b}
Equip it with a full set of diamond armor and a diamond sword.
Get a command block (because of 100 character limit instead of 256 before 1.11).
/summon Zombie ~ ~1 ~ {PersistenceRequired:1,Equipment:[{id:iron_sword},{id:chainmail_boots},{id:chainmail_leggings},{id:chainmail_chestplate},{id:chainmail_helmet}]}
/summon Skeleton ~ ~1 ~ {PersistenceRequired:1,Equipment:[{id:bow},{id:chainmail_boots},{id:chainmail_leggings},{id:chainmail_chestplate},{id:chainmail_helmet}]}
Upgrade the world to the latest version.
Observed results:
The inventory of the zombies, skeletons and armor stand is shifted and some items are deleted.
Expected results:
Items should stay where they were and should not be deleted.
