Can't claim plot: says already claimed when it's not

Students stand on an unclaimed plot but receive a message saying it's already claimed.

Symptoms

• Plot appears unclaimed (no name shown)
• Student stands on it and tries to claim
• Error says "already claimed" or similar
• May affect one student or all students on a server

Possible Causes

• Server state is out of sync — plot data says claimed but UI shows unclaimed
• Student already has a plot claimed on the same server (only one plot per player)
• Rare race condition when multiple students try to claim simultaneously

Workaround

1. Have the student try a different plot
2. Check if the student already has a plot claimed elsewhere on the server
3. If all plots are broken, everyone leave and rejoin with a fresh Buzzy code — this resets the server state
4. As a last resort, an admin can unclaim plots via the admin panel
