Some feedback on the ghost ships. I just ran across an Expedition battlecruiser from the Missing Ships mod (the one with 6,000 max crew and 2,000 required), and it requires 2,000 marines be stationed on board the ship. Last ghost ship I found was 200/200, so I guess it's one marine for every skeleton crew required? Not sure what the formula is, but it does seem a little excessive. My own thought would be maybe 10% or so would make sense.
Whatever the case, awesome mod and thank you for making it.
