Because:
1. I was unable to install it, it crashesh every time. I did separate thread for that, nobody from DCS answered or helped me. They just dont care, as always.
2. I was forced to uninstall my DCS 2.5 OB and install it again.
3. None of my mods working with last update. And now i should delete all of them.
Despite of that, new 3D models are just amazing. Nice job, ED.
