When I click "Enter" on an Old Mine Crashed UFO mission, nothing happens. I can supply the save file if needed, but looking at the console the problem is obvious:

<source lang="txt">
g_notu is a developer cvar.
g_nospawn is a developer cvar.
Can't find maps/mine.bsp
</source>

Indeed mine.bsp doesn't exist, even though mine.map is there in /usr/share/ufoai/base/maps. I'm using the same ufoai on the same Arch distro as in [[http://ufoai.org/bugs/ufoalieninvasion/issues/5607|the previous bug report I made]].

I tried to compile it but I'm not sure how to (the same error occurs when I try to compile a .map with an already-existing .bsp):
<source lang="txt">

It may be an Arch-related problem, but I suspect something was broken with the map that it didn't compile for the package maintainer in the first place?
