Without giving away any spoilers, I have a mission to launch a probe at a certain moon... First try I launched the probe without realizing I needed to arm it, and it just crashed into the moon. After getting a second probe and arming it before impact, it reached the moon, then flew a short distance away, then flew back, then flew a short distance away, on repeat until it finally ran out of battery power.

Not sure if I'm doing something wrong or there is a bug in the logic... The moon is also at a different set of coordinates than the mission journal indicates.
