This use to happen to me though I cannot recall why. I think that if you give it some time it might resest. Try going to the other one(tram/fel) and seeing if that works. I'd fall out of my chair if anyone bothered you in fel if that is a worry, I use to solo it all the time a year ago and only once had to deal with people showing up.
At the same time I'd go and get another T-Map and give it a go....I seem to remember having to do that but it's been a very long time.
Leave a protector on a boat and see if you can farm up those fishing pinks, that was the real reason I bothered doing it.....24 pinks was a huge score.
