Why old guides disagree
Older Demo discussions describe replacing or rerouting Haulers because individual removal was not convenient or available. Those posts explain the search demand, but they are historical context and should not override current Early Access behavior.
Current management path
The collected developer response and current community reports point to Drone Admin or the Drone interface for individual management. The exact UI labels, menu position and unlock step are not stable enough in the collected evidence, so those details are 待确认.
Route changes are related
If the real problem is a Hauler taking the wrong route, route management may solve it without deletion. Keep removal and routing as separate answers so a troubleshooting page does not promise that one action fixes every drone problem.
