all my minecoins have disappeared

Hi and thanks for reaching Microsoft Xbox gamer's community. My name is Josef.
I'm an Independent Advisor and a Microsoft Xbox user like you.

Hope you're doing great today despite this Smxcazy

Do you know if something new appeared in your Minecraft account? (Like a new world from the marketplace, an skin, etc)

If not, you may need to reach Minecraft support to see what happened to your coins

Nothing got added, my coins came back but then when I quit and came on my game they went again, they came back when I bought mine coins, but like I said, they disappeared again.

Hello Big Joe 410,

Apologies for the confusion. There was an error that arose with our daily maintenance that caused a file to fail. This caused users to briefly see what appeared as no account at all. We have hotfixed this issue, and you should now be seeing account information
that is accurate up to yesterday morning. We are currently working on getting this information up to date to this morning. Apologies for the inconvenience.

I've had the same problem...

Had a village of breeding villagers, went mine clearing, came back, villagers gone! all of them!!

Went to next village, bagged a couple and brought them back to my village. Went mapping, came back, all the villagers gone.... In both villages!!

Found a third village, buried deep in sand, with 3 villagers... Left everything alone except for clearing some sand, and put in a couple of doors to the village huts.

Went back to my base built an automated chicken breeder/farm/cooker...

Popped in to see villagers, as it the other side of the map to my base....

Villagers all gone!!!!!

There are now no more villagers on the map, every time I left them alone they DESPAWNED!

zombies are spawning in houses even if you cover the floor with torches I play pure survival two of my naturally generated villages have been decimated one left in one village 5 in the other created two new villages in one house which was lit up zombies
spawned where there was at least 7 villagers luckily I was there and exited without saving after that I covered the floor of my houses with torches and one still spawned in another house so its a bug one
