League of Legends has been temporily thrown into chaos after Riot Games developers apparently reverted every Patch 13.1B change originally shipped onto live servers on Jan. 26, possibly accidentally. While no official word has come out of Riot yet, Dot Esports expects it will be hotfixed very quickly.
Almost immediately following the Patch 13.1B removal today, League nked queues across the globe were disabled, suggesting Riot techs are already on the job.
