The bug
Deleting a world no longer logs that the world is being deleted. Instead, only "Attempt 1..." is logged. Previously, there was another message that was displayed before this, indicating that a world was being deleted, "Deleting level NAME".
To reproduce
Launch the game, with logs enabled, in an old version (such as 1.12)
Create and delete a world
✔ A message is logged before "Attempt 1..." is logged indicating that a world is being deleted, "Deleting level NAME"Launch the game, with logs enabled, in the latest version
Create and delete a world
❌ No message is logged before "Attempt 1...", which makes this message unclear
Expected behavior
A message would still be logged before "Attempt 1..." to indicate that a world is being deleted, and which world is being deleted.
I can confirm this behavior in 1.18.1.
