Beta 19 is a small update which mostly focuses on bugs and contains the following fixes:

• Fixes various crashing bugs.
  
• Fixes issue allowing both research and fill orders to be queued on the same hex
  
• Automatic pausing when the app window loses focus is now optional in the settings, and turned off by default
  
• Fixes AI issue that caused them to occasionally wander away near the end of the day for no apparent reason
  
• If a wait order has been issued, it is now removed automatically when you issue a standard move order
  
• Fixes issue where they couldn't build 4x4 floors from adjacent floors, and needed closer access
  
• When starting a new world, burning large pine cones as fuel is now disabled by default
  
• There is now a chance of receiving a small rock when digging soil
  
• Adds Cyrillic and Korean fonts for better localization mod support. More fonts to come soon.
  
• Fixes crash when using international fonts at low resolutions
  

It might be a little longer until the next update now, as I want to tackle a few larger tasks. But it should still be ready within the next week or two.

Thanks again for all of the feedback and bug reports.
