There was a bug where players with strange characters in their names caused lobbies to crash. It has been resolved (you need latest update to see the fix).
Regarding updates, I will be looking into making the day/night cycle fairer to those people who play less between sessions.
Infections and Bleeding can be cured overnight if you have medicine, but I am working on a solution for allowing you to cure either with things like adrenaline or medical kits. Perhaps it will be a better chance based on your medical area's level and if you have a doctor.
Your feedback is extremely helpful. I am especially interested in what kinds of missions you'd like me to add.
Thank you!
