I tried the in-game updater and experienced two failures.
First, the installer did not quit out of the running version of Bitfighter. This is an annoying, but longstanding bug, and I propose we address it by asking users to quit manually.
Secondly, after the install appeared to work properly, I was launched back into 019d. This is a new problem and will require a closer look.
A third issue is it appears we are including bitfighter_debug.exe with the installer. I think we shouldn't.
And, I think, mystery solved. The bitfighter_debug looks like it is the new build (though I can't run it to confirm), and the copy of bitfighter.exe that we are shipping is the old one. See

Actually, after rerunning the installer again, we may not be including a copy of bitfighter.exe after all; the one in my install folder may be the old copy, not a new copy of the old file.
