Overture used to work fine, now it doesn't

[Ideka]

After some time, I got this apparently fixed.
Turns out it was the other way around: I had previously deleted some libraries (libopenal, libogg and libvorbis) and so the system-installed versions where being used, and it seems an update of (some of) these libraries made them no longer compatible with the game.
Look: https://aur.archlinux.org/packages.php?ID=31299

Thanks for your effort and time, Urkle.
