i've unlocked all 3 dungeons on the Act1 Battlefield.

dungeons 2 and 3 all have 3 levels.

dungeon 1 however only has 1 level. i can see the stairs that will take me down to level 2, but there is no way to get to them. its all empty space (only one path joins up to the section i am in, but that path is blocked off by a wall!!!!)

and it would seem that the majority of quest items from BF1 are on those 2 levels (dungeon's 2 and 3 havent got any quest items in them...)

if i can capture a screenshot i will post it here (dunno how to capture screenies tho ingame)
