my black reach in skyrim is bugged or glitched because there is no ground on some places and small hills are missing what do i do?

It seems you have a rendering problem. You can try to change resolution to force the game to "refresh" the landscape.

how do i paste a screenshot to a text

unfortunately you can't yet... I believe the minimum post's is 10 before you can post a picture... but then hit the green link and add the pictures address. depending on the site you have your pic's at is how exactly you add it to the link... I generally use the drag method... just drag the web address of the pic into the link box and hit ok.

Try going in and out of a doorway...which should reload the cell... an elevator or Sinderon's lab door should work.
