We are having a problem with a realm created a few days ago. The realm itself does save, but progress from outside players randomly resets. The realm was created on my husband's account, and I have played it daily. Today I log in, and I have no inventory and am back at the original spawn point. We have restarted the system multiple times, double checked to make sure I was signed in and synced. Not finding any reason for this, except that it is a bug. The same thing happened to my Son yesterday. He made progress 4 different times, and each time he came back, he had nothing.
This is still happening after 1.2.1.
