Hi everyone,
a new patch (v0.5.019) is out with some smaller fixes:

• fixed prison priority button sometimes shown on default components
  
• fixed error when item got removed from zone in count mode
  
• fixed very rare error on animal eat job
  
• fixed destroyed colonists sometimes shown in grave select menu
  
• disabled prioritize items which are already in a zone (area tool)
  
• fixed some smaller things
  

Cheers!
