EA gave Madden NFL 23 players an unwanted gift last week: corrupted save files. The publisher said on Saturday that anyone who tried to access the game’s Connected Franchise Mode (CFM) during a server outage has a 60 percent chance of losing their saved data forever.

The initial server issues occurred on Wednesday, December 28th and stretched into the following day. As a result, EA says files were corrupted for anyone who logged into franchise leagues during that period. (Save files should be unaffected for anyone who didn’t.) Unfortunately, EA’s development team estimates it will only recover 40 percent of the corrupted franchises.

Making matters worse, EA tweeted on December 28th that “users should now be able to play CFM without issue” — three days before delivering the bad news about lost saves. After apologizing, it encouraged affected gamers to “start a new franchise as the mode is up and running.” The publisher also directs customers to follow the Madden franchise account on Twitter for further updates.

The Madden series’ franchise mode first appeared in Madden NFL 99, with the rebranded CFM arriving in 2013. (The latest version lets you control a player, coach or owner throughout a simulated career.) Considering how many hours it can take to build your league, it’s hard to imagine gamers with borked saves being content with EA’s advice to start a new file.
