[Spaced Out! Hotfix] - 456169

Hi friends! We've got an update with a fix to the reactors! It's been really fun watching them blow up, but this will make them blow up a little more predictably. Let us know if you find any other issues, and enjoy!

• Fixed crash that could occur when one researcher takes over from another at the Atomic Collider.
  
• Adjusted Research Reactor reaction parameters. It begins reacting with a minimum of 0.5kg fuel and stops reacting when fuel drops below 0.25kg. This should address some unexpected meltdown issues.
  
• Adjusted Radioactive Contaminant count on Research Reactor's nuclear waste output.
  
• Adjusted Research Reactor construction time.
  
• Restored Medical Pack recipe to Apothecary.
  
• Deprecated Virtual Planetarium building in Spaced Out! until a new utility is implemented.
  
• Large Solid Oxidizer Tank is prioritizable.
  
• Beeta Hive animation updates and fixes.
