Hey all, (I'm new), I think I can shed some light on the arty issue as I too have it. For me, I have the .pbo's in my addon folder. I don't know what other people with the problem have done but I didn't want to have deal with the mod folder as I'm running CO on Steam (hassle). I think maybe making the arty work for when the .pbo is in the addon folder might help? Also someone mentioned effects on other non BWM items (standard D30 and M119 which seem to have disappeared alltogether even in editor lists etc.), this happens for me. Otherwise the detail and amount of new vehicles/weapons in this mod is awesome, keep up the good work!
