For some reason, when I split parts into different groups and try to launch the ship, the groups won\'t save. For example if I had two groups: Group 1, Which contains Part 1 Part 2 And then I had Group 2, Which contains Part 3 Part 4 When I hit launch, it will merge group 1 & 2 together and I\'ll end up with one group containing all 4 parts. I also tried using a fresh install of KSP .14.4 and used the version of mechjeb included, and I\'m still having this problem. Any idea what could be causing this?
