Hello @linuxgurugamer, and thank you for your awesome work on many mods !
When I save a second orbit for my Hohman transfer calculation, the SOC window goes empty, and the console get spammed with OrbitalElementExecption : Resulting eccentricity cannot be less than 0.
I use RSS/RO/RP-1 and the orbit calculation was around Earth.
Here is the Player.log
