We have been playing on 1.16 previously. We decided to give 1.17 a go, so we reset the realm in order for it to run on 1.17.

We started the bedrock realm a couple of days ago and all was going smoothly untill today 06/23/2021 17:00 UTC. 

We were playing on the realm with no heavy gameplay like a villager-breeder or mobfarm whatsoever. From one moment to the next the game said something along the lines of "You were kicked from this game". Turned out that in affected every player on the realm. When we logged onto the realm again, it somehow loaded the previous world that we had on minecraft version 1.16

This basically means that we lost all the progress we made on the 1.17 realm, so this is such a shame. 

We rebooted the realm and it loaded in version 1.17 again, but the world we previously had in 1.17 was gone. Now we just wait and see if the issue appears again.
