I don't know where else to ask this so I'll do it here.
How do I go interstellar without using wormholes? I don't mean engine wise or anything but mechanics wise. When I leave the the SOI of Kerbol, my trajectory disappears so i can't plot a maneuver node or anything. This is my first time using any interstellar mods so if there's a better place to ask this, or somewhere that explains all of this, please let me know.
