Uh, well, within a few minutes of playing my ship got sunk, I went down with it, and everyone kept shooting at me. I could actually even still shoot my broadsides...but I don't think I was hitting anything. I had to logout to fix it.
Twice I boarded crewmembers ships and couldn't man the cannons. TPing back to land and trying again seemed to fix it.
What else...OH! I leveled up to 35, and instead of giving me 35 points like it said, it gave me 350. Seriously - I went from 1600 to 1950 (and have a screen cap of it, in case anyone wants to see). My voodoo must have been the same deal, but I wasn't paying attention.
That's one I hope they don't fix.
Edit: The not being able to man cannons has now happened with to doors; I couldn't open any.
Also, my compass disappeared.
Oh, and the error on my HP is only visual...sadly... As soon as I get hit, it takes me back down to where I should have been. It still says 1960 (I guess it was 360 not 350...I'm very observant

), though...
