This is our first live update and it is also a complicated one for our server hosters. So please try and be patient.

What will happen is your steam client will update to 113772, and some of the servers will be on older versions. They will still let you connect but will cause issues, such as:
◾Not being able to open doors
◾New features not working

If you have the new steam update, filter for 113772 but realize there are only the six dedicated experimental servers up now.

We estimate it will take about three hours for all servers to update.
