Cuz at this time, I was on the office scene when I pressed the home button to put my phone to sleep for a reason. I removed the background process as well. Then, moments later, I turn my phone on and run the game, I often get an error "Unfortunately, WD S1 has stopped" then...I reinstalled it and lost everything. Now I have to start all over again because of this error. Just in case. I need that save data location so I would backup it before I reinstall the app. BTW, that error never bothered me though. But what really bothers me is LOSING MY SAVE DATA. And pls. fix. Tnx!
