I/O Error in certain maps

[Sinmir.6504]

I traveled into Snowden Drifts with a character, it got the loading screen for a while. then the I/O Error. Was fine traveling through the Foothills to get there. Opened with another character, just did the dailies, was fine getting to Ember Bay for the vista then Siren's Landing for Forager. Then had no trouble getting into the Borderlands. But there seem to be a persisting I/O error  for Snowden Drifts for me. Also, because the character went through the gate from the Foothills and is now in Snowden Drifts, I don't have access to the character either.

You can try this Command Line Argument for stuck characters:  https://wiki.guildwars2.com/wiki/Command_line_arguments#-prefreset

Good luck.

Scan your harddrive for bad sectors. It might be the reason.
