In core mission 8 I go out, the trawler tries to flee, I catch it and board it, it follows me back to sydney, but when I get there it stops dead, doesn't appear on the ecdis, and can't be towed either.
I've attached a screenshot of me trying to tow this thing on full power but going nowhere, and I've tried to let it follow me but it won't.
I've also gone back and retried it and this is the second time this has happened
