I have every file I need: info, tilesets, etc. It works fine with 2x textures enabled or if there is only one texture pack.
Game just picks wrong file when there is 2 packs with 1x and 2x textures and you want 1x.
If you activate mod when game already launched, it loads 1x textures as it should be. But on relaunch it always selects 2x.
