Just wanted to make you aware that often time if I save and exit right after a battle, the game reloads starting that there are still ships. Even I tap anything and then try to move in the world map, the speed is stuck at the normal x1 speed. I can't fast travel across the map and have to start a brand new patrol. Also, clicking save and exit usually freezes the game, it still seems to save though but it does freeze.
This is on android.
