Ships and tonnage totals doubled
 

I have just completed the first mission in OH11 got back to base did upgrades and rearmed etc saved the game and come out of it. I know I sunk 11 ships but the figure at the end of the game says I have sunk 22 ships and my tonnage is doubled has anyone else come across this

Yeah, I've had that happen to me too. Every time I'd exit to the menu the last screen before the main menu would show double the ships and tonnage. It was driving me nuts.

Until I started my next patrol and everything was back to normal again. I don't know why it happens, but it happened.
