16.71.1311, seems to works fine, but only as far as damage is concerned (and damage-based effects, like Psychedelic=yes). Ares effects (EMP, AE, etc) are still always applied to air objects, no matter what threshold is set.
Don't know if this is part of this blueprint, though, since i believe those are being applied in a different way.
This is working as intended and not a bug. No weapon that fires at a ground target is able to damage flying targets.
