Yeah, I figured it may get be worth mentioning, since it’s kind of a show-stopper if you’re trying to get somewhere on foot on the Mun.
@Adenosine Triphospate Nope, no time warping. In fact, it won’t let me. I’ve definitely tried to time warp while walking both on the Mun and on Kerbin.
Also, I’ve confirmed that the twitching doesn’t happen on Kerbin, so that reinforces my theory that it’s related to the lower gravity of the Mun.
