A campaign I put a substantial effort into is now bugged, and I can no longer launch any crafts from my VAB. I already had this problem with my initial campaign on the day of the game's launch, and after messing with launch locations, the only solution I found was to delete the campaign and launch craft in a new save. However, I think I'll just keep this save around until a future patch addresses this bug. I'm glad the community can aid in developing KSP2 by reporting bugs and gameplay qualms. I wish the devs the best and assure all that I am not complaining.
