The highly anticipated PC beta for Fallout 76 just wrapped up, but it didn't exactly go smoothly: chief among the problems was the loss of the game files thanks to a Bethesda Launcher bug, and many (including PCG's Fallout 76 expert Chris) were forced to re-download the whole game. Depending on your connection speed, this could dramatically affect your ability to get any meaningful time with the beta.

To make amends, Bethesda has made an adjustment to this Thursday's beta session – it'll now go four hours longer than planned.
