Patch notes 0.7.0.5

This is a minor bugfix update.
[h2]Fixed[/h2]

• A bug that caused educated workers to be stuck eternally mining resources
  
• A bug that educated folks to be invisible. The invisibility skill has been un-taught and all folks are now visible when they should be.
  
• A performance improvement bug that caused tiles to remember their resources for too long, which sometimes tricked buildings into thinking there was no room for more production
  

[h2]Changed[/h2]

• Based on player feedback, the default value for allowing house upgrades has now been set to "Allowed". Some players found this confusing, and in most cases players want the option to turn it off on demand, but would prefer it to be on by default
  
• You can now select a fishing area outside the player area for fishing huts
  

[h2]Improved[/h2]

• The folk information popup window will now let you know which tool the person is missing when they don't have their work tool
