Male toons with body 2 and head 10 are also missing their heads,
https://imgur.com/a/iwzdtMP so far its only 4 of the 12 playable species and i only tested it with imperial class Sniper, female toons don't seem to be affected with this at all
hair/complexion/scars/skin & hair color have no effect, so its just head 10 and body 2
(EDIT) just went back and tested all classes and races on both sides, it only affects Chiss, Mirialan, Togruta and Rattataki, Body 2 Head 10
