With Malverk, if Aura is installed and at least one other texture pack is present in the Mods folder, clicking on Textures (options menu) makes the game crash. If no other texture packs are installed, the Textures window opens and shows no texture packs (not even Aura.)
Possibly a Malverk issue?
Aura's fantastic, by the way. Is there a way to support this project?
