Here's the changelist for the latest beta patch available now.

The main addition is an autosave every 5 minutes if you open the map. This is a fairly experimental feature that really requires testing. Let me know if anything weird happens.

• Prevented unnecessary resolution switches at startup
  
• made sure when you wipe a scenario it saves the wipe immediately
  
• added an autosave moment when opening the map
  
• cleaned up some memory usage
  
• prevented some weirdness with naval batteries and guns without damage models

Additionally I noticed two reports on crashes, if this happens, getting your log files is my only clue as to what happened. These can be found generally at C:/users/username/appdata/locallow/wiredproductions/bulwark/player.log

Generally at the bottom there might be mention of an error,, copy paste that into any forum post , that is super helpfull

Cheerio,
Tomas
