As of now, Lonely Cave, The Grounds, and Ficho seem to be having problems still. I was lucky to get into Cherika Valley though with one of my characters, but other than that that's the only map I know works for me currently. Not sure about Bonfire and Seaside, though some people claim that those maps are also fine.
I honestly thought I was the only one with this problem till I stumbled upon this thread. B')
