Uh, this isn't a test server issue per se (I'm not a test server player) but I noticed this recently as I've been doing missions:
Before, IIRC, the end of mission pop-up provided us a button labeled [Return to Haven].
Now the end of mission screen has a button labeled [Continue].
This isn't really a big issue but I think the former was more appropriate as we aren't going down one level, we're going back to Haven...
[EDIT] Thanks to whichever moderator relocated this thread; standing in the shower later, I realized it would make more sense for it to be in suggestions.
This is thread 80000!
