Even though the world format did not change in 26.2 Pre-Release 6, the game requires that a world last opened as soon as the previous pre-release be upgraded “due to underlying changes to the world format” before being opened, edited, or recreated.
How to reproduce:
Launch 26.2 Pre-Release 5.
Create a world and exit the game.
Launch 26.2 Pre-Release 6.
Click on the same world again.
-> ❌ The “Play Selected World” button changes to “Upgrade and Play,” and the “Edit” and “Re-Create” buttons are grayed out.
Expected result:
Worlds from 26.1 or later would be able to be opened, edited, and recreated without needing to upgrade it.
Observed result:
Worlds from as late as 26.2 Pre-Release 5 cannot be opened, edited, or recreated until they are upgraded.
