First Post, newb condition in full effect. So I've got a pair of map sat 4.0 dev build sats out there, mapping up some kerbin and mun action. But when I exit the game and return later, the map data is all gone, and the sat's have to start mapping afresh. I have 'store raw data' on. I've not the first idea how to troubleshoot this, but I'd like some help getting the scene so map data persists between game sessions. Do I need to do some I'm doing the steam thing, got a couple of mods installed (Mechjeb2.08, map sat 4.0 dev, some big ass parts mod I can't recall the name of . . .) Do I need to be doing something with ISA_MapGen.exe or am I just missing some obvious thing? Also? Hi!
