I love that! Definitely going to start using it. I have a couple of questions though. First, I want to make it so each R&D centre upgrade adds another node research slot, is adding this what I'm after? sign([R]-[I]) Second, after testing, it looks like a scene change is required for this to work. If I begin researching two or more nodes then switch to KSC, all nodes begin researching at once (and will unlock if I warp to complete at this point). I have to switch scenes (e.g. enter the VAB) before it functions properly. Does this count as a bug? Unrelated to this, I encountered a bug earlier after recovering a vessel with an exploded part, but forgot to grab the LOG file . I remember reading somewhere that this is a known bug, so is it worth me trying to repeat it for you and pasting a log? (FYI It was a 'Launch Stick' from Sounding Rockets by RoverDude that exploded). Thanks for the incredible mod! KSP feels so meaty now I can't reach the moon 2 days into a new game.
