On the second thought, tt may be deeply rooted in the AI algorythm for WP opener. I think it operates this way: open WP from HW system to some other system and then use that system as an operational base for WP opening. However, if AI can "see" some other, unreachable, system due to random ship move event, it tries to send a stellar manip. ship there. Since it is impossible, it goes into total mental block
