I accidentally created a multistage missile with a separation distance that was way, way too low, meaning that the buses are being destroyed by AM fire before they separate. The second stage missiles have enough range to work properly, the only mistake is the number I entered in the "maximum separation distance" field. I built hundreds of them and started a fight before I realized my mistake.
Is there any way for me to modify that value for the existing missile model my fleets are carrying and I have stockpiled, or do I have to make a new version?
