Inconsistencies in lift forces applied to mirrored parts

for some reason the "missiles on the left are going to act really werid after their separation for some reason , its happening a lot lately and i dint know what causes it (the right win is the wig that was mirrored)

Dev Notes: This is actually related to the drag recalculation code which was incorrectly marking structural panels as not occluded and enabling their wing physics when they shouldn't have any wing physics at all.
