So which is it?!
 

Starting my 10th patrol (Aug 30th 1940) I got a popup "Base changed: Lorient" (I think it was Lorient at least). However, my orders still say "Dock at: Willhelmshaven". I got a radio transmission about a new base available though, and my patrol grid is off the west coast of Morocco. Still, the orders are to return whence I came. Which is it?

As for mods, I am using GWX and SHIII Commander, which I might just uninstall - it seems I use it for nothing except load the game. I don't like to give rewards which the game doesn't, I don't like selecting my own patrol grid. The profile is nice, with the extra things like ship names, but is it enough?

Anyway, any help gladly accepted :)

Go to lorient (or wherever it said). That's worked for me in the past (i.e. you will be able to access boat upgrades in the new location). It's too bad the change doesn't upgrade your orders though. On the other hand, they were printed before you left.
Maybe a radio message should remain to remind you of your destination.

Usually you will get another radio message telling you to go to Lorient.
I don't use Commander, quite happy with GWX 1.03 as is.
