Sure i'll try and find the screenshots i saw that featured the not to good english.
Well the first one is this one:

Most of the English is good actually (although i am sure some of my teachers might disagree
) It's more the "Dwarves' underground" you mention
For example, "I need the maps of Dwarves' undergrounds." Well it just lacks a The infront of Dwarves and it's good.. although i was very close to posting a deeper explanation with several different versions which i think would be better (Damn you university education !)
And then there is the second choice:
"Well informed people told me you have dwarves' maps"
and that one isn't right either, and i am somewhat certain that you can't say "dwarves' " in this case it's because it pretty much says he's got all of the dwarven nation or nations maps or some specific group of dwarves maps, but as far as i know it's an unknown group of dwarfs maps he is looking for..
So in this case it would be better to say:
"Well informed people told me you have dwarven maps"
Oh dear.. I actually went ahead and did some grammar stuff.. sorry about that
Otherwise i recall something with a screenshot showing how you leveled up and the level up screen saying something not quite right either.
Hope this helps.
