Errors or bugs that significantly affect the game are only changed weeks later instead of immediately. So that basically represents an imbalance between classes. The GM changes things without notice that have a big impact on the game without even paying attention to the original episodes or listening to the community. Anyone who doesn't follow the GM dictator as expected will be immediately muted or even banned. Then the VIP system with 10% more drop rate naturally has a big pay-to-win factor
