I don't know about u but both of my pirates where lv 0 when I logged on to pirates.
It's just a hiccup in the account infrastructure somewhere. Annoying but should stabilize soon. No data has been lost.
That has happened before
The game was under maintenance, that happened when they changed the old pirates to the inventory pirates, with the loot and all. And now I'd guess it's for the Infamy, has something to do with name tags.
