Bunker Alfa works correctly at the moment; however, the timer for its refresh has been changed.
 
What's changed
• The timer for Bunker Alfa's refresh used to launch after the elevator's descent. That meant that characters could spend an unlimited amount of time on the bunker's surface, since the timer would start the countdown only after the descent into the bunker.
• Now, the timer launches immediately after a character enters the Bunker Alfa location, even if they haven't gone down yet.
 
If you entered the Bunker Alpha location, then exited the game, came back some time later, and then went down on an elevator only at that point, it might seem like the bunker refreshed prematurely, whereas the timer just started the countdown the moment your character first entered the location.
 
                               
Important!
If you intend to complete the bunker later, don't enter the location beforehand, so that the refresh timer doesn't kick off prematurely.
