Whenever you save a design with a Frigate Missile Launcher, they turn into Anti-Fighter Missile Launchers.
This was originally mentioned by snowdrop over here, but I decided to repost it as it’s a fairly obvious bug and that post is at the bottom of a thread about various things. Also I was writing this post before I noticed someone else had already mentioned it.
As far as I can tell the bug is in the frigate_antifighter_missile.txt file, as it has the
name = "frigate missile"
line, which should probably be changed to something other than frigate missile. frigate antifighter missile, perhaps?
I’ll test making that change and report back if that fixes it.
Edit:
Yep, that was apparently the problem. You can fix it for yourself fairly easily by changing the name field in the file located at \Gratuitous Space Battles Beta\data\modules\frigate_antifighter_missile.txt to anything other than “frigate missile”. I have no idea if this will break challenges, so please change this file at your own risk (or keep a backup. It should be officially fixed by Cliffski sooner or later anyway) - I don’t know whether GSB checks for matching datafiles in the online modes yet.
