When Trying to delete a world in 1.15.1, the world will still be there even after confirming the deletion to the world.
Expected Result **
The world would be deleted after confirming the deletion of the world.
Actual Result **
The world stays there even after confirming deletion of the world.
How to Reproduce **
Launch 1.15.1 Minecraft
Create a 1.15.1 World
Delete the World After Creating It
This is honestly a pretty big bug for survival world players, if they wanted to create a new world but going to have the same name then the two worlds would get confusing and the world would be a waist of space.
Cannot reproduce. Please check if that's still an issue for you in the latest 1.15.2 stable release.
