Player locks are disappering 

Looking at your QuarryLock plugin, I can see the issue. The locks are disappearing because the plugin isn't calling SendNetworkUpdate() after placing or modifying the code locks, which is necessary to persist the changes through server restarts and ensure proper saving.

Here are the specific problems:

1. Line 249 - After setting the slot, no network update is sent
2. Line 524 - After updating the parent in the coroutine, no network update is sent
3. Missing network updates on both the code lock and parent entities
