I made a personal BAIN package including all your other AV packages where each can be optionally installed. Bash wouldn't detect the Hagravens, Wolves, and Snowy Sabercats packages because (weird, imo) their screenshots folder was named "screenshot" instead of "screenshots". Could you append the "s" to those folders in future versions so that they don't have to be renamed manually? I love this mod btw, the whole AV concept in general too.

Edit: To add to that, because of the fact that all AV packages are installed in the "SkyProc Patchers" directory, Bash can't seem to detect them as having anything to install, probably because it's a custom directory or something. Bellyaches' AV Package only had a "SkyProc Patchers" folder, with everything else inside that. Normal, right? Well Bash wouldn't detect anything. What I did to fix it was add a "screenshots" folder to the same directory as the "SkyProc Patchers" folder, then added a dummy image file inside that. Now Bash is able to detect and install every file (after selecting 'has extra directories', it wouldn't even allow me to select that before adding the screenshots folder).
