If you select a group of objects to rotate, they will rotate around your mouse pointer. The game engine isnt smart enough to rotate an entire airfield and keep things aligned.

My cut and paste options work fine. Check your entries in your conf.ini again, you may have something misspelled.

You can rotate entire airfields, groups of buildings etc. Before you do that you have to tick Edit/Rotate Objects in the menu in order to keep everything aligned.
