Strangest bug name ever.
Since the newest update, (.186) the hybrid hives I have encountered have started the old indecisive "going backwards for a few seconds, then forwards for a few seconds" behaviour, causing them to get fairly stuck deciding to leave a planet or attack a station. I don't think this happens on your own worlds, but it definitely does on neutral, and possibly hostile worlds. I don't have a save of it happening, but if I come across it again I will try to post one.
Not sure if this counts as a fully fledged bug, but figured I would let you know.
