When you enter the main guarded entrance there are two miners speaking to each other.
Once they are dealt with, you drop the bridge/gate and two bandits appear, once you have dealt with these two, you go down to the locked up storage area and there is a guard to deal with.
At this point you go into the main chamber and deal with three more. So 8 in all.
Now if you enter the mine from the cave entrance closer to River wood there are only 6 guards/miners.
The guards you find after lowering the bridge/gate when you use the main entrance, are nowhere to be found. I would have expected to find them somewhere after the locked up storage area.
Of course it has no effect on the game but seams wrong and bugs me.
