Somthing wrong with the dungeons plugin?

OK, so this is the fourth time my dungeon has been reset to a way it was quite a while ago..... Im starting to wonder if there is somthing seriously wrong with the plugin, butcause the rest of the server did not reset with my dungeon. Its more of inconvienance but its still annoying. Every time I work on it for more than a couple hours it just resets the next day.
