So, it was patrol #17, the first patrol I had with the GWX mod installed, I set to all ahead one-third, and proceeded to plot out my course.
Overwhelmed with all the new features, and the fact I wasn't the only one in port anymore (more ships sailing around me? Awesome!) I used the external view cam to see all the ships and stuff.
Me: This is incredible, Look they even got swastikas on them!
W.O.: Please don't embarrass yourself again Captain, remember the light-boat incident?
Anyway this went on for a good 5 minutes, until my crew started complaining about how we were taking damage, and there was this horrible grinding noise, so i looked back at my ship
and this is what i saw.
It turns out the navigator won't use the course you plotted without you telling him "return to course."
Who knew?
