I have the same issue as described on this topic : http://forum.game-labs.net/index.php?/topic/5608-totally-bugged-stuck-in-the-water-ow-without-a-ship/(but i couldn't reply to the existing topic)
It hapened around 10 am (GMT +1), i didn't buy anything before sailing, i have only one ship, so i don't think it's related to something i did, maybe just bad luck.
I tried teleporting to capital, which just moved the location where i am stuck.
Restarting the game, waiting for an hour, checking game files integrity hasn't helped.
If i understood the previous thread well, an admin has to move my player to port if i want to be able to move again?
My IG name is the same as on the forum.
Thanks

A big thank to anyone wh tried to help me in the ingame chat, even if it didn't solve my problem.
