Hey, I've been having an issue with the BDB mod. Basically, I get this error message:
And none of the parts are installed. If it helps, it occurs in KSP 1.9.1 and 1.9.
I have a question over the Saturn V. How do I put the Apollo Command Module and the Lunar Module together? I mean, where do I attach the Lunar Module to the Command Module together, and, where do they go on the Saturn V?
