Triple K

All riiight Bob's back in action! Thanks for all the help! - - - Updated - - - Well Bob's safe and sound at the moment, but my space center seems to be bugging now, especially the building with the radar dishes(can't remember the name of it), don't know why. Whenever I try to click on the aforementioned building, nothing happens, it's outline appeares, but that's it. And if I click the building with the kerbonauts, then exit, the whole space center does the same, not without the outlines and all. Any ideas?

Hey! New to the game and newer to the forum. So I wanted to drop a rover in from high altitude near the north pole, and because of ships/debris disappearing after 2.5km it was hard at first, then I downloaded the Lazor System mod and increased it up to 22km. Things just got a lot easier, dropped the rover, got a perfect touch down, then landed the jet,recovered the jet. Everything was awesome, just untill the moment when I wanted to return to the rover, just to find out it was missing, with Bob Kerman inside it. He was listed Missing in Action, and I thought if I deleted him from the lost section in the building with all the kerbanauts he'd respawn, so I clicked the RED X next to me(I know, I know). So now he's nowhere to be found. Waited for around a month of ingame time, 2 days of real time that maybe he'd respawn, but nothing. Wanted to edit the persistent file today, just to find out he's not in it. Probably because of clicking the RED X, I know, but still, is there any way I can bring him back to my game? Thanks for the replies in advance!
