So i recently encountered a weird glitch, that cloned Jebediah Kerman. I crashed a plane near the capsule he was in, and when i switched to his capsule, something weird happened. I was unable to revert or go to the space center. When I went on EVA he was walking around normally, but it was hard to control. When i went to go back in the pod, he froze on the latter. I switched to the pod, and Jeb was in it, although we was also outside. I tossed the other Jeb out and they were indeed both Jeb. Here's a link to a video i posted.
