I used MechJeb2 last night on a vehicle I landed on the Mun; this morning the MechJeb2 menu isn't appearing anywhere for that one vehicle. It appears as normal for other vehicles in the same game, as well as the VAB/SPH, and in the default game. I've tried restarting KSP as well as reinstalling MechJeb2. The only settings I've changed between sessions was some EVA controls, and that was only impacting kerbals on EVA (duh). So what did I set for that vehicle that's hidden MJ from me altogether, just for that vehicle, and how do I undo it? :-/
