identical world seeds will not produce identical dungeon interior layouts on each identical map... the dungeon location (on the map) is generally in the same place, but the interiors will be random each time, and vary (randomly) in size and number of rooms etc.

Same here. First couple swamp crypts were just a couple rooms. Was thinking iron was gonna take forever. Last 2 crypts had a ton of iron in them. Took 3 or 4 trips, even with a cart, to empty them.
