I just checked and i do not think it has been updated to version 2.1 yet.
It is updated to 2.1 Tried it for an hour and it worked just fine. I am aboput to run it for another hour and see how it does again.
Tried it for two seperate hours and both times closer to an hour it would stop and sit in the boat again.
It still stops after running for a while but i let it sit. After you get kicked out of the game for not moving it loads back on the boat and starts runing fine for a few more games.
