I found a problem when clicking on a ship in the planet/ship list. Every time you move a ship after that, it re-centers on the last ship that clicked on in the planet/ship list.
Three things will make this go away.
Clicking on a ship with moves left in the planet/ship list and using them.
Clicking on a planet in the planet ship list.
Turning on the 'Allow the computer to automatically go to the next ship with moves' checkbox in the menu settings. (it will however comeback if you uncheck the checkbox.)

I saved, quit, and restarted and was able to reproduce this bug.

Scincerely,
