Just last week, Bethesda sent out a letter to fans warning about potential bugs in the Fallout 76 beta. Now that it is available on PC and PS4, though, an extremely odd one has cropped up. For players on PC, clicking any button in the game’s launcher will actually delete the entire game and necessitate a redownload.
A Tweet was put out this afternoon warning all players on PC to not click any buttons in the client “for the time being.” As discovered by Kotaku, doing so would erase the nearly 50 GB beta from users hard drives. A follow-up told players that if they see a progress bar for a download, to let it finish.
