A response from GoE, the Minecraft Marketplace map publisher:
Hi,
Thank you for contacting us, this problem started because of a change in the latest minecraft 1.16.100, we already found the issue and submitted a fix and hope that it will get released soon to the marketplace. As soon as the fix is released you will see an update popup on the map logo on the marketplace and when you update this bug will get resolved.
Should not take long for this update to go live,
We hope that very soon you can get back to enjoy this map like always.Best regards
The GoE team
And my response to them:
Thanks so much for your response, we'll look forward to the fix. In the meantime, can we refund the mine coins so they can be spent on a map that currently works?
Thank you again.
I'm not playing on a server. I have downloaded an offline map from the Minecraft Marketplace and am playing it in single-player, offline, locally on my Xbox One.
I have contacted GoE and requested a refund and they have not responded to that request.
Broken maps are being sold on the Minecraft Marketplace with no comment system, no refund system, no way to even alert anyone that the maps are broken.
Kids buy these maps and then lose their money, unable to play the map or get a refund.
