I am really not sure how this card works. I found this in an English manual

Shipwreck: You can only roll twice. You score diamonds and gold coins as usual
and ignore all other symbols, including skulls. So, if you roll 3 or more skulls on
your first roll, you can still roll a second time. Skulls still cannot be re-rolled. You
cannot go to Skull Island.
All your points scored in this buccaneering quest are doubled.

I hope someone can give me a very clear explanation:

What happens on BGA with the points:
if you throw 3 skulls in the first throw (can you still throw again?)
if you throw 4 or more skulls in the first throw (can you still throw again?)
if you end up with 3 skulls after the second throw
if you end up with 4 or more skulls after the second throw

It doesn't help that there are different rules in different countries...

In the german and the Dutch manual you canNOT go to skull island with this card. The skulls are just to be ignored. You will get doubled points for coins and diamonds.

In the online version it says you can.

The online version: You can go to skull island but you are still not allowed to reroll more than once. If you have more than 3 skulls after your reroll, you score according to the rules of skull island (but your turn still ends).
