It takes me back in time.

A problem that already happened to us twice...
We are 5 people in a realm, we were in the end all normal, however at one point he took us all out of the server and took us back in time approximately 20 minutes, we did not care and we continued playing to recover our things.

We left the game, that was yesterday, today we entered and we went back in time, we returned to the same point of the previous time but we already had more game time, I don't know if you could help me recover my inventory or see what to do.

Thanks.
