It happened to me today (crash to windows) while i was in south shroud as botanist to get Gridanian Walnuts, constant crashes to windows (FFXIV stop working), tried to log with other character in other zone and no crashes. After trying to have the time needed with my main character to do a fast teleport out of the south shroud (i went to limsa) i was free of crashes there.

I guess something of the data related to south shroud map is broken so i will have to reinstall the game...

please develop a repair tool for the game -_-
