Hey Café Owners! This small patch targets several crash sources and stability edge cases.

🐞 Bug Fixes

• Warehouse save crash: Fixed an issue where the Warehouse inventory could contain a null reference, causing a crash when a save/autosave was triggered.
  
• Restocker travel crash: Fixed a rare crash when the Restocker tried to restock a shelf that was being unloaded during level travel; queues are now cleared or re-targeted safely.
  
• Repair Station autosave crash: Fixed a timing issue where removing a CPU from the Repair Station exactly as an autosave started could cause a null reference.
  
• Login line cleanup: Fixed a dangling reference in the login machine queue after sleep/wake cycles that could lead to a crash on the next assignment.
