Re: Basement causes severe terrain errors
This looks like one of the quirks of the build system and has been around for a long time. If you put a basement under a house on a raised foundation or raise a house on a flat foundation with a basement under it, the terrain raises like that. To fix it, just drop down to the basement level and grab the big arrow in the center and drag the basement down until the terrain is flat again.
In your pics though, you show raised terrain around only part of either building. I'm guessing that the basement is a partial basement, not a full basement under the entire building. It that is not the case, then something else is going on.
Hope this helps.
