Summary:

World cannot be created on 1.12.0 Nintendo Switch build

Impact:

Our map passed initial Mojang review and now cannot pass certification. The map is summer themed and we hopped it would get out by mid July.

Repro Steps:

Attempt to create 'Tropical City Resort' world on a Nintendo Switch.
Wait while the world is being generated.
Observed Results:

After a couple of seconds of loading, the following message will appear "A newer version of the game has saved this level. It cannot be loaded."

Expected Results:

World can be created without issue.

Screenshots/Videos attached: Yes/No

Yes

Regression Builds:

N/A this map was made with 1.12 in mind. And after we converted the build from Java, we only used 1.12 builds do include mechanics and further develop.

Unfortunately we cannot test on the Switch. We don't have the hardware and i think we also need a dev licence. All the info in this report comes from the failed certification report.

I made sure and checked the version i had last opened the map with, with an NBT explorer.
