How do you get this custom ui to work, because it always crashes on me. I did this:
$ ./ufo +set fs_gamedir uidev
And got this at the end:
FS_RemoveFile: remove /home/christian/.ufoai/2.5-dev/uidev/keys.cfg
There are still 1 opened files
Error: Received signal 11.
And all I can see is the loading screen for about 1 second.
