Something weird happened. The same ship got sank twice within a couple of seconds. I would provide a screenshot but the forum doesn't allow images bigger than 16 kb, which is the equivalent of a smiley.

Dimples attacked you in the Caribbean sea. You lost! 2013-12-04 13:52:32
Xnat attacked you in the Caribbean sea. You lost! 2013-12-04 13:51:41

The text box in the Caribbean Pirates says that Dimples sank my ship at 13:52:32, but nothing about Xnat.

I'm not sure of what happened. Did Xnat lose but the report shows he won?
