Nullifier Target not damaged by titania's dex pixia

[treg.]

When a Nullifier Target appears in Ukko (Void) i can't be killed using titania's dex pixia pistols. (The target can however be killed by excalibur umbra's exalted blade so the dex pixia being some sort of exalted weapon can't be the reason.)

You can only break the nullifier bubble but not inflict any damage on the actual target.
