Additional notes:
When changing jobs but having printers placed down, a notification should pop-up stating our current number of printers and players should be asked if they'd like to proceed in changing jobs or not.
Example:
You currently have <number of printers> Printer(s) down, are you sure you want to switch jobs?
The options should be something like:
This way, people will realize they have printers down and won't just switch jobs and lose them.
