I started playing Saga of Survival on my computer through the Plarium Play app.  I then attempted to play the game on my tablet, but that started a new character.  I thought that if I used the "Connect to Plarium ID" on my tablet, that would allow me to resume the game I was running on my PC.  Turns out this overwrote the game on my PC. How do I unlink the account so I can resume my previous game?
