Minecraft PE 1.18.0.23 for Android

The developers unexpectedly released a test version of Minecraft 1.18.0.23 on Android. In this update, they fixed a bug with the disappearance of old worlds.
Bug fix
In versions 1.18.0.21 and 1.18.0.22, players encountered a problem. Old worlds were not displayed in the menu, although they were stored in the game folders. To get out of the situation, users had to manually move them from the old folder to the new one.

Now the saved worlds on the external storage will be displayed correctly. If you have not yet had time to start survival in the new worlds, then continue to play on your maps on the new versions without too many problems!

We hope the developers won't make such serious mistakes in the future. Just in case, always save your worlds before upgrading your version of Minecraft.
