QvQ dream game

It a great game I have played it for around half a year, it is entertaining and u will love to come on everyday because there will be so many thing to do that u can never stop playing it. However like I said u have to be on everyday or else someone like me might be depressed when I missed out a character(event character) or I never completely upgrade that character Q^Q. But still it’s a great game even if u did’n fully upgrade the character to max everything, before the event goes there is a chance that u might get the upgrade resource from some other event but it will be a time to test your luck and skill because most of them are from ranking event and it’s hard to get your self to 1st place (well u don’t need to be in 1st place it just give u a lot of upgrading resource be around 10-50 will be good)unless u are lucky enough to get a good character and weapon for that event quest...
In conclusion it’s a fun game :P

Loved the game- but the bug hasn’t been fixed yet

I adore this game, I’ve played it for just over a year now. I enjoy every aspect of the game- however, due to the bug that causes the app to close- I am unable to do anything anymore. If I open the Quests menu, it shuts down, if I open the scouts menu,it shuts down, if I try to pick a supporter, it shuts down. Sometimes this works fine, on the other hand though, when I try to enter the medal scout, it ALWAYS closes. For this reason, I missed the Halloween medal scout and I think I’m going to miss the current medal scout with Argo. If possible, I know it’s very difficult for developers to find and fix certain bugs but the game I’ve come to love is basically unplayable now, I can’t do anything without it shutting down.
I want to uninstall and reinstall the game, yet I’m afraid I might lose my diamonds. Offloading and reinstalling doesn’t fix the problem though.
