While playing on my Bedrock Realm with 6 of our 22 members, the realm out of nowhere disconnected everyone. When we all came back online, we had all lost roughly 15 minutes of progress, basically back to when the last automatic realm backup had occurred.

How it appears:
No apparent trigger. Possibly an issue with automatic backups? Definitely seems server sided.

More Info:
I had been warned about this bug this morning by a friend on Discord, but didn't think anything of it since there weren't any highly voted bug tracker issues about it, like the nether portal glitch you guys made so much worse.

I am making a separate post since most the others seem to be occurring when no one is online, or just after someone logs out, however ours occurred when multiple people were actively playing.
