On my game there is a boat, a short walk south of Frossel cave, with an apothecary satchel, chest, and strong box in it that when you walk over to them the open option does not show up. Whether this is supposed to be like this or it was overlooked in the creating proccess it doesn't matter to me just wanted to know what was up with it.

Hmm, I seem to remember something like that. Programming boo-boo.

I noticed this too. I think after I entered the nearby cave (Frossel) and came back out, the various unselectable containers in the boat had vanished.
