Hey everyone, so I just unlocked the atmospheric intakes, but I'm having a bit of a problem. I can see them as unlocked in the R&D screen, but they don't show up in the parts menu for the SPH. I've checked all the other tabs just to be sure, and it's not there. I've also tried it in sandbox mode but it's not there, either. I've also tried reinstalling all the mod files, and that didn't help. Anyone have any ideas on what to do?
