Recently, we made a change to how the nightly manages its current working directory (to make managing servers more sane, to make launching the command line utilities less mysterious, and generally have less spooky action at a distance, and to potentially support multiple profiles in the future), but unfortunately, that change broke the launcher. I’ve worked for a few hours and found that there seems to be no good answer to our problems without reverting the changes we made, and we can’t really justify reverting those changes.
As mentioned, the root issue is now that we’ve made changes the launcher has the wrong working directory. In order to fix that, I had to move the launcher to the proper location (or do a change to the working directory for the starbound executable, which is what the change was originally intended to prevent.)
Eventually, we decided to move the launcher to the same directory as the executable, but now it’s screwing up because Steam wants it to be in the same location as the current stable.
We can’t change launch paths by branch, it’s set per depot, not per build. We’re sending in a support request to Valve on the matter. It might be as simple as “just add another launch option that’s valid on the other builds, but invalid on the stable, and it will try them all.” And I’m hoping it’s that simple. But it’s not something that I want to test out right now without knowing for certain.
So what does this mean to you?
The nightly on Windows and OSX (OSX was broken as well by the same change, even though it doesn’t use the launcher), you will need to launch the executable directly, rather than through Steam, until further notice.
