I've search the forums for info about these, but almost nothing shows up. I'm sure it must have come up many times, but apparently just in PMs and not in the forums

What has to be done to take care of these??

This warning is not terminal - there are a lot of buildings without shadows. Attach shadows to your building Nifs, if you want to fight the warning nevertheless (look better too). IF a shadow is there, it must be called SHADOW, for the game to alighn it properly.
