Famine, shipwreck, DLC, how to find treasure, treasure map, and the mechanism of finding treasure

Although there are many things in a treasure, it is divided into three lists:

1. trophy: be sure to give it to everyone on the list.

2.random_loot: Make sure to give one in the list.

3.chance_loot: the probability is for everyone in the list, which may or may not be all.
