I can't get the dynamic to work for me, either in chrome or firefox, colonies or dwilight. Is anyone else having this issue? the mini-map on the travel page works, but doesn't show the sea zone names until after you start your travel, and then it's too late (fortunately, I could find the zone number, and then search for forums for that number...but that took me 10 minutes).
I'll open a bug if someone else can confirm the issue. Could just be my PC.
