Well,
as said my sloop was pretty full of nice stuff and I made an volcano explode via gun powder barrel. I died :)
I returned but I was on my ship at differen place and treasures gone :)
I saw videos when pirates died and they returned to their sunken ship or what so ever and treasures floated...
I returned to my place in less than 10 min and all gone?
Is that the way it is? Where can I learn about that?
