I have tried installing B9 procedural wings on my ksp 1.8.1, but it keeps stopping at "verifying expansion: breaking grounds. I have had b9 aerospace before b9 procedural wings, and it worked fine. now, with b9 procedural wings uninstalled, it isnt working, and i am getting the same error. has anyone encountered this/know a solution to this? seeing as most of the crafts from kerbalx that I like have this mod, it would be great if it worked.
