Bug fixes

• Fixed an error on startup for players who had never launched the game before.
  
• Fixed some scenario levels being selectable when they shouldn't be (some scenarios start from a given mastery level).
  
• Fixed some of the leader skills that grant free projects, which sometimes wouldn't be free anymore.
  
• Fixed resources already sent to space projects not being kept when loading a save from previous versions of the game (before v1.6.x). Now resources are kept. If you were affected and made progress in your game, the space project resources won't come back as the info was lost. If you have saves that were saved before 1.6.x but not overwritten, they should load properly, with resources sent to space project kept. Our apologies to people affected!
