Hi all,

Just another small update to address a few things.

• Fixed a bug where the player's heir wouldn't take over some businesses
  
• Fixed a bug where you could end up hating yourself
  
• Increased the zoom height
  
• Slight increase to walking speeds
  
• Mine ore range extended and surveying upgrade removed
  
• Farm animals no longer require oats
  
• Farmhouse can now produce small carcasses
  

Cheers,
Stardog.
