I've found a bug (I think), but I don't have an account on Github, so I will post this here. I have a few "realism" mods installed, including RemoteTech 2, Mission Controller extended, FAR, and a few others (ioncross life support, deadly re-entry, some parts). I installed Kethane .8.1 a few days ago when it was released. I opened up my career mode save, which already contains the beginnings of my remotetech comm network. When I go to the tracking station, all the kethane grids work fine. however, the stock UI buttons become unclickable. I can't switch ships, delete them, or even exit to space center, and have to alt-f4 to quit. I removed kethane, and the issue disappeared. It's an odd issue, but it has stopped me from using the mod. I have a feeling it is a conflict with remotetech 2, because both mods have visuals in the tracking center. MCE also has a window that opens here, but it is present in the VAB/SPH as well and the button issue did not occur there with kethane installed. I'd love some insight into what is causing this, I used to use this mod quite a bit and would love to add it back to the game.
