The patch bugs out in save games after acquiring the "Pollo Power," making it impossible for players to leave chicken mode and essentially blocking progress. The patch was live long enough for some players to download it, and Drinkbox says it may have automatically downloaded for PlayStation Plus members last night. To fix the issue, PS3 players can delete Guacamelee entirely and re-download it, and Vita players can save to the cloud, then delete and re-download the game.
"We hope to release a fix for the patch (as well as the downloadable content) as soon as possible," Drinkbox says. "Really sorry about this!"
