Just discovered this bug the hard way upon approaching the Mun with Jeb. I really thought I'd have to sacrifice him as he was suborbital with no fuel left, except 4 landertrons which just fired him back into space. Only just managed to put the craft down after separating the landertrons into 2 pairs. First set killed horizontal as well as accelerated him towards the Mun so that the second set intended for killing off the vertical descent didn't send him into deep space. Managed to safely land the Kerbal way doing ~55m/s and using the poodle engine as a crumple zone TL;DR Please fix this! Would love to see it working with RemoteTech as someone else has mentioned
