How to trigger:
Open the game and create a world
Turn to Settings (Game Options)
Enter “Accessibility“
Open the “Closed Captions“ option
Place any block
The subtitle of sound reads “block broken“, but it should be “block placed“
Why this happens: It is probably due to the fact that placing a block and destroying it shares the same block sound effect
