Put the summary of the bug you're having here

What I expected to happen was...:
After I completed a map and traveled to the Nether with the other person in the realm, we logged off and expected our newly filled map and goods from the Nether to be saved the next time we logged on.

What actually happened was...:
The next time we logged on to the realm, all our progress had been lost. This happened twice. Our map was no longer filled in and all our goods from the Nether were not there. Our levels were also reset to what they were before our map completion/Nether adventure.

Steps to Reproduce:
1. Open realm
2. Complete a task/adventure in the realm
3. Disconnect from the realm

4. Log on again
