Stolen ships

[BoneCrushR]

So if you capture from the spanish either the Golden Fleet Man O War or the San Felipe in the Defense of St. Pierre you won't be able to go into spanish ports with them cuz the spanish will instantly recognize it as "stolen form them" and attack... same goes for Victory in Cromwell's Dispatch and the english. But I remember reading a post about how to make them forget about these ships so u can land with them in their ports. Can't remember tho if I read it here or on Steam community forums. But if I remember correctly u had to either delete or modify or delete a line of code.
Anyone has a lead on this? Anyone remembers this post or how to do it?
