Making me restart my game for doing nothing wrong!

If I could give this 0 stars I would. I wanted to go to metal parade to complete a quest, and when I try to tap on it it says my game session has expired, when I come back on. terms and conditions pop up when I hit accept, It shows the beginning of the game!!!!! I dont know what I did wrong or if this is just a glitch, but it could happen to you, so I wouldnt get it. But please fix this, and can I also get my stuff back!
