@MojangSupport Been playing for a while, teaching my grandson how to play. Great game. Logged in tonight and respawned in a weird location. Lost my good armour and enchanted tools. WTAF!

Have you loaded into the original world and do you have any backups? Try loading a backup to see if the older save data appears. If you're still having trouble, let us know what device and Edition you're playing on and we can continue assisting! ^AM

Nope didn't work. Lost 13 levels, my enchanted armour & weapons and my cats are stuck in the sitting position. Clearly a glitch. Apparently this is common.
