Genshin Impact fans are reporting that malicious players are using its co-op feature to infiltrate other players’ worlds and delete in-game items like seele, chests, and elemental totems, preventing them from progressing.
Right now, the issue is primarily affecting players on the Chinese server, but given the issue appears to permanently “brick” progress – even if you reinstall the game or play on a different device – all players are warned not to join any stranger’s co-op game until the issue has been resolved.
According to some players affected by the issue, the “destruction is irreversible”. This video, for instance, shows how an elemental totem – used to get around the world – was deleted, bricking the player’s time-limited challenges and preventing them from progressing.
