Actually, I read the rollback thing, then logged out (my minimap wasn't loading) and tried to log in, all AFTER the data corruption and that. BTW I was logged out for less than a minute, I doubt my boat was stolen ^^
In that case, it is weird. I have heard similar reports in the past, though, so there may be some actual bug with the boats. I cannot think of what, though, and I've unfortunately been unable to reproduce the problem myself.
