The same thing has happened to me twice already; the most recent being two days ago.

Both times, the apparent cause was being on a server that crashed. The game became non-responsive (for example, I couldn't tp or kill anything), and I wasn't able to log out the usual way. Had to CTRL/ALT/DEL to exit the program. This resulted in my pirate becoming trapped in PotCO Limbo.

I sent in bug reports, and got the standard response that they were looking into the issue and that it would be patched at some point in the future. I ended up not being able to play that pirate 'til a day or two later (seemingly after they performed their nighttime "maintenance").
