I play Minecraft on my account at my house, then my brother plays Minecraft on my account at the other house while I’m not playing. All of a sudden, some of the blocks disappear of what my brother had done.

Hi Mojang,

I live in 2 houses and both of those houses has an Xbox one. Those two Xbox one’s have the same account(LuckOPgecko). I play Minecraft on my account at my house, then my brother plays Minecraft on my account at the other house while I’m not playing. All of a sudden, some of the blocks disappear of what my brother had done.  I really appreciate if you fix this issue. Thank you.

Sincerely, 

 Customer
