i think you made the whole situation even worse because of this survey post. people will always be negative towards any fault from your side. imagine the real life situation, real society, where you'll be constantly judged for every mistake you made. i think you don't have to listen to community and decide what to do with the game itself.

i understand that people who are responsible for the events are not robots and they are not flawless.

whatsoever, you make it even worse postponing the fixes cause people tend to be impacient and they can't wait that long. i guess the best way out was to instantly roll back the servers, to prolong the maintanence and send the compensation for waiting.

right now the inactivity untill 10th of october is sort of unbearable.
it's hard to do something 100% right in this situation and there will be a lot of complains anyways.

the bug with the sakura's gift mission - you may compensate sending 35 packs on mail because it's the exact amount of packs you would get for free doing sakura's missions.

box with sailor sakura and playboy sasuke - you may make them meme ninjas since they are not that much used tbh. but it sounds super absurd. another variant - you may give the players a choice (for those who abused the bug) - either you take away those ninjas or you make them pay the normal price of the boxes, so it won't seem extremely unfair for other players because only those who paid for the ninjas got them. so you're not losing anything basically. and also you can send compensation for the inconviniencies in sbw or matsuri, for example.

sakura's gift boxes price - it's likely the event is the same as it was before. you increased the drop rate but increased the price aswell which sound pretty logical so i don't even understand those who are complaining. i think the whole noise about this is only because of the 2 times when the items in sakura's gift where extremely cheap. so just ignore people. you've done ok with this.

hope that i helped you. this were just my thoughts about this situation.
