Yeah, seems like they honestly didn't know.I can translate a bit. After all agreed to save and restore, one of the VNA team members said "so we'll all see the map, it's not fun to play anymore". This makes me think this guy thought everyone would see the map, meaning he didn't know that it was a violation. Also, the fact that songsong did it on stream really confuse me whether they cheated on purpose or not.
Either way, the ban is necessary. They should know the rules, as they have participated in different tournaments many times.
