The Bug:

My Minecraft worlds on another device got deleted after changing my username

Steps to Reproduce:

• Share a Minecraft account on two devices (for example Laptop and PC)
• change your username on one of the two listed devices
• Worlds on the other device will be gone (at least it did that when i changed it)

Additional Information:

 I changed my name from "Claidermann" to "Lachs_Thunfisch" and noticed, how my worlds got deleted on the other device

maybe you could change my name back to "Claidermann"? Else i would have to wait 30 days to change my username, but i really would love to keep playing this month.
