OK, here's a screen of me on another pirate's ship, literally seconds before this post, so clearly the perp is around Padres on Abassa, and no one can stop them, free to do as they please.

No loot yet and the ship just left port with no hostiles nearby.
Yeah, fun!
Now I'm speculating here, but sailing was drastically different in POTCO, where ships were never hidden from view, be it enemy or friendly.
In TLOPO, we can't see enemies 100 yards out most times, and suddenly a friendly pops into view like they were just launching, except they've been there the entire time.
Even if this isn't related to the mystery sinkings, it's a problem and has a deleterious effect on game play and sailing specifically.
Perhaps sailing needs to be revisited and coded so it resembles how it was intended?
Just a thought.
