I'm trying to get some ships into the Hashinsk(51,37) system. I killed the lockdown drone there 2 turns ago, and then last turn another was fired, which is up this turn. I've discovered from previous turns that you can't get in the turn after a drone dies - it takes another turn. But after a new lockdown drone is created, shouldn't I still have a turn to get in? i thought that was in the rules.
Anyway - the message I'm getting doesn't say I can't get in because it is locked down. It says: "Fail to jump as this ship cost is a Destroyer(3) and this system only accepts Frigate(2)." However, the star system says "Max ship class [Mauler (7)]". One interesting thing about this system is that the rip currents it creates are Frigate sized, so maybe there is an error there.
