Didnt work at first for me, then instead of using ComeAbout, i just turned my ship without 'moving', and then after leaving the wheel.. i retook the wheel and sailed through the island! hehe
Tried it on tortuga and port royal it worked, except the buildings etc on the islands werent visible like in prior times i had it happen by mistake.
