Upcoming maintenance.
We will be performing some maintenance on the game to move location on Steam sometime over the next few days.
You may experience some disruption to the game whilst this is happening, and unfortunately we cannot specify exactly when it will take place as we are dependent on Steam for the finalisation of the maintenance.
Hopefully there will be no disruption, but this is to let you know just in case! :) So apologies in advance if any blips happen and we'll let you know when it's complete :)
Upcoming maintenance.
