Bonus Treasure Locations

[redimap]

Has anyone taken the time to track down all of the bonus treasure locations?
There are 15 listed.
I know where one of them is, and I found a couple of others over my various runs, but I haven't noted any others yet.
If no-one has bothered, I might do it myself and share.
I assume that once you get all 15, you will be able to score a hidden achievement.

Unlike Port Royal 2 the bonus treasure locations are just that, To my knowledge they are fixed but I believe there are more than 15 or at least they change bonuses throughout the game and are repeatable. I think I have seen Sailors, Cash, Cargo and a combination of those.

I have found five bonus treasure locations so far. The locations are fixed. The treasure types cycle through sailors, cash and cargo, as far as I can tell. The actual qty of cash or cargo is random within a certain range. The number of sailors appears to be 90-100 % of the crew capacity of the flotilla that discovers the treasure.

Are you sure about this? How do you know?
What's the achievement name? I don't think there is such achievement.
Those bonus locations are not randomized?

Each time you find a location, a message comes up, e.g. "Found Goods in Hiding Place 868 barrels (Bonus 3/15)", or "Picked up 100 stranded sailors (Bonus 5/15).
It seems to me that if there are 15 bonus treasure locations, that are difficult to find, then there's probably an Achievement attached to the completion. Since the Achievement isn't listed, it is probably one of the 6 hidden achievements.

I just shared a screenshot of a test run in a std game with Port Royale as the home base. The bonus treasure spawn locations seem to be either the same place all the time, or within very closely related regions. I won't be certain until I/we have found all the locations.
I'm not sure whether the locations spawn randomly over time (ie. Using a set location and pattern, but with a certain time-based lag), or by another method.
I can confirm that in the game i'm currently playing at Professional/Random that there are two locations that I know about. I can collect from one location or the other, and each will provide the same reward - Sailors. I can then travel to the second location and it will provide cash as a reward. From this, I can guess that at least at professional level, there can be more than one concurrent bonus treasure locations.
This is different from Port Royale 2, which would spawn the artifacts randomly but in a serial manner around the map. ie. You pick up one, and you might know the locations where the others will be, but you don't know which location has spawned next.

I just encountered one of these. There was no marker for this and just a message at the top, then disappears quickly. I just realized what you're talking about. I got 2/15 it says. It was north of Tampico, close, in some kind of fjord region.

About the hidden achievements. I don't think any of them related to this hidden treasures.

Thanks. Haven't seen the entire list before. Anyway, i'm not really interested in getting achievements. I just like to work out all the dynamics of a game i'm interested in.
Regarding the bonus locations:
I'm currently working my way through a simple search for all of the bonus treasures in a standard setting game. I'm making detailed screenshots, saves, and marking up a full map of the locations.
I'm still not sure if the locations spawn in sequence as they are discovered, or if there is also a timed release of them.
I am currently at 9 locations, and i'm confident now I'll get to the full 15 soon. It's just a bit of a grind.
Once I have all 15, I'll share my results and a summary of the mechanics that I can confirm.
Then hopefully, other players can test it out and see if there are any other quirks to them.

That could be useful for me too. Thanks if you would share your findings.
