I did the same today, contacting Live Support about this issue. As I shared with you all, I told them the same.

Billy: Ahoy!
Don: I read your description and I am very sorry for any inconvenience.
Billy: It;s okay,
Don: We are aware of these matters and the Dev's are looking into a resolve for it.
Don: In the mean time, please try moving to a different Ocean, that should resolve the matter in the mean time.
Billy: This happened two days ago
Billy: Doesn't happen often, but it was strange the way it did as I described it.
Don: No, its not something happens all the time, but it does occur.
Billy: So it's not unusual for three pirates to stand before a portal and only one of them can't see it due to a bug?
Don: Correct.
Billy: okay
Don: But its also not really common either.
Don: Is there anything else I can address for you Captn?
Billy: Not at all
Billy: I like to test when I play
Billy: Thought it might be insightful
Don: Awesome, glad you are liking it.
Don: Thank you for chatting with me Billy.
Don: Fair winds Matey.
Billy: Thank you
info: Thank you for chatting with us! Please take a moment to fill out our Experience Survey.

It's not unusual. Don told me what I needed to know. I'm sure they're working on fixing it. I figured sharing what had happened in my particular circumstance might pinpoint the source of the problem, and thus, get this bug fixed much faster.

It is true, in fact, that I do like to test while I'm playing. It's my favorite quest.
