Seems like the "warp" setting has been messed with and is causing this issue. Handiwork of some mod unless it was a mistake on your part. The game's scale has nothing to do with this. If you have the developer console enabled, type warp
& it shall show you the value it is set at. Default is 1. Set it at 1 (type.. warp 1
) for normalcy to return. If you don't know how to enable developer's console, search the forum, there's a tutorial on it.
