If you set the regions right, it will be impossible to antiwarp from center... however, if a base is too close to center, the antiwarp radius can affect center. Unless it's obvious, antiwarping center is almost never done on purpose. Also, ASSS 1.5.0 supports this new region property 'noReceiveAntiwarp'. So you just set the center area to that, and you can't be antiwarped in center. Magic! DCME 3.4.16 supports this new region property, FYI.
