PANews reported on November 5 that according to Video Games Chronicle, Ubisoft's recently launched NFT role-playing game "Champions Tactics: Grimoria Chronicles" encountered a major vulnerability. A player achieved "automatic victory" through unknown means, causing other players to be unable to play ranked matches normally. This player (nicknamed Schilleri11 or Paulstar111) automatically won every online battle, and the ranking list showed that he had played more than 56,000 games.

Affected players complained on the Discord server that every time they were matched with this player, they would lose the game unconditionally, causing the game to be unable to proceed normally. The game's Discord administrator has stated that the team is aware of the issue and has banned the player, but some players have reported that the account is still active. Ubisoft is working to fix the vulnerability, but the incident has caused strong dissatisfaction among players with the stability of the game.

The official Twitter account of "Champions Tactics" announced that the team has found a solution to the matching issues last weekend and is formulating a compensation plan to give back to players' patience and support.
