same thing happened to me but on the same computer I always play on. I had completed two of them and one to go on two of them. I now have completed one with one to go on 3. This game has got me about 4 times on similar stuff no one has compensated me, and I've spent a lot of money. Good luck
I had 6 billion dollars the game glitched and kicked me off when I logged back in my credits were gone. I love the walking dead game and it's the only real problem I've had. I spend a lot of money there and it's a lot harder to get 6 billion then it is to lose it.
