...that bug will be fixed in the add-on along with;
- the "auto popup" chrono in TC (never did see an explanation of why it does that)
- the dive plane graphics glitch
- the destroyer collision sound for the rubber dinghy
- radar sweep switching off every time you go to the radar screens
- engine at "all stop" every time you return to a saved game
- having to "return to course" every time you return to a saved game otherwise the sub fails to follow your previous "saved" plotted course.
Small but quite annoying bugs in my view, particularly after all the patches.
