I have a similar tale from last night's multiplayer.

We were sailing on our karve, looking for the trader and swamps with visible crypts, but all we found was Plains everywhere.

We would sail north, only to see Plains, turn east only to run into more Plains, go west and run into Plains, sail south and then west only to run into Plains. Of course there were also storms and fogs along the way.

Almost every time we were next to a swamp a fog descended, so we could not see anything, especially crypts or turnip seeds in the swamp.

There was, too, a Fuling swimming after us from a tiny spot of Plains, in the middle of the ocean, that was just big enough for the creature to stand on.

We sailed for two hours, finding nothing of interest except two of those floating islands, but we already had 100 chitin stored on the ship and the rest of the storage space occupied by tin, so we didn't stop for those.

We ran into a serpent at one point, and it combined with a storm that bashed us against the ocean floor and rocks took our boat down to 50% "health". Escaped from that beast thanks to the wind, for once, being on our side.

Another serpent later on killed me after I fell of the boat while fighting it, at which point we'd mostly sailed in circles trying to NOT run into Plains and made practically zero progress overall.
