Affects Version/s: 126.96.36.199
Fix Version/s: 188.8.131.52
First off... I have never opted-in on any beta program for Minecraft on Xbox One.
A few days ago Minecraft updated from v1.2.13 to v184.108.40.206 (beta) via auto update on Xbox One.
Today I got a message in-game notifying me about the error to push a beta to non-beta users. I followed the the instructions there to revert from v220.127.116.11 (beta) to v1.2.13 again by deleting the game and reinstall. All my savegames was synced to the cloud.
After installing / rollback to v1.2.13 and loaded my maps they are now corrupted with bunch of missing blocks (huge areas). Pretty much all areas i have built anything. My maps in the cloud is corrupted too.
This is a major error / bug.
Multiple reports from users here:
There is also tons of similar comments under the informational post about this from in the Minecraft Game Hub on Xbox One.
And finally... How do I recover my worlds that I have poured 100+ of hours into with my friends? Microsoft told me that you control the cloud storage and can revert to earlier versions. In my case 1.april is before the update.
