But I’ve been getting this: “Network error or server is disconnected. Check your internet connection. Restart the game.” Error.
It kept dropping me out of the game.
Go to your Google Play Games.
Settings -> Delete Play Games Data.
Delete your Forge of Glory data, then reinstall the game.
This will erase your progress but it will fix the disconnect error.
In my opinion there’s something with the game save.
Probably the game save had errors.
