I encountered an odd quirk where I hid my Privateer out in a native coastal village after I raided Spanish shipping, but while I was healing the Privateer apparantly the Spanish LB/cultural border enveloped the coastal village entirely, including out at sea. For some very weird reason, it would not let me take my Privateer out of the village without declaring war on New Spain. Privateers are supposed to be able to cross cultural borders even without a ROP right? I'll try to post, unfortunately the game is on an offline computer, so I have to copy the files on to this one to post (this is just a lousy laptop). Its such a rare situation, it might be a regular issue with C4:C and not just the mod. I've actually been curious how the game would handle a situation where a native civ gave up a settlement that had another civ's ship(s) in it, haven't had that happen yet though.
