AutoCity/Silent mode not breaking

[calors22]

Describe the bug

I noticed that when using it (AutoCity w/ silent mode) on servers updated to 1.21 or even in singleplayer mode, it cannot silently break a block, and it doen't happen until the player manually changes to a slot with the pickaxe, either with the mouse wheel or with the numbers on the keyboard

Steps to reproduce

1. enable autocity w/ silent mode
2. try citying a fake player
3. the render cube disappears but no block gets broken
   a quick fix would be great, thanks
