Strange issue..

[frau kaleun]

I would say, start a whole new career if you didn't already, with start at sea unchecked. From the same base at around the same time period.

If you don't start at sea in the new career, then we know it's not the coordinates in the game files, or something Commander is doing across the board. It's just an issue with the one career you were already playing.

Which is where checking the coordinates for DeparturePoint Long & Lat in that particular Career's folder would come in.

Granted, I don't know exactly how those files are read by Commander or the game or what exactly to edit to fix the problem for that particular career, but at least we'd have narrowed it down some and know it's not an issue with the game files or Commander overall.

If we don't have any luck figuring it out here, it might not be a bad idea to ask about it in the stickied Commander thread in the Mods forum, might get additional input that way.
