Don't mind me, just a few more bugfixes.

Fixes

• Crash: Upon eating food after drinking water to clear your food queue
  
• Crash: A couple crashes relating to a few shopkeeper interactions in Co-op*
  
• Bug: Charged Magic 101 book does not work
  
• Bug: Chain lightning fails to cast at odd MAG values of 7 and above
  
• Bug: Game softlocks if one player descends the stairs in Co-op while the other player's controller is disconnected
  
• Bug: Only one player can control the quit game dialog box
  
• Bug: Portal only works when placed on floors and ceilings
  
• Bug: Enter/Return key doesn't work as a fallback default to confirm in textbox pop-ups

*Multiple players talking to the shopkeep at once may still act strangely but it at least shouldn't crash any more.
