No file edits, no mods enabled. The only thing I've done is copy chcg3_head_PiercingEar_low.png (which looks like it should actually have been chcg3_head_PiercingEar2_low.png based on chcg3_head_PiercingEar1_low.png & chcg3_head_PiercingEar3_low.png) & name the copy chcg3_head_PiercingEar2_low.png. This has, understandably, seemed to fix the issue.
