Boat issues

[Soala]

It happened to me today for the 2nd time. I have quite a serious issue with boats on CP Island.

I recently tried to use a boat I've found on the beach and as a result I was warped into a ridiculous level made of sand.
Then I tried to use a boat from the harbor, I got on it fine, took it out from the storage and when I got outside, I was standing on the black water, with everything of course black around it, and the boat was going, going.. I was not even on it !

I unsticked and got on it a bit later again, and same happened but I was now warped from where I was (north of the castle) to the complete north of Westford !

What the hell is wrong ?

I've made a few screenshots so you can see what really happened.
