Servers will be brought down at 5am pacific for between 1-2 hours.

We are publishing a small update to address the following items (as noted on the recent test server update):

• A fix for door states - there were cases the displayed door was in the opposite state the server thought. This should address these cases. Please report additional cases.
  
• Assorted recipe fixes.
  
• Reduced the size of the large zombie hordes as a test.
  

Client version will be 0.103.1.52648, Steam Build ID will be 672803, and the download should be under 100MB.
