Could someone with reliable access to Innoxia or Discord or Github mention the "issue" below, please? 
(I haven't found any similar issue reported so I *think* it's unknown.)
It is
not-really-a-bug ... I just found this problem while experimenting (in v0.3.9.9) so
the actual situation can not happen in the 'standard' game
"yet"--hence, it's
not an actual "bug", yet. (I hope that's clear.

)
Set-up:
*
Your character race has been
part-demonic through much of the game, and
* It's now
after you finally meet Lyssieth.
The "Near-Bug" problem starts somewhere, here:
* The next time you meet Lilaya, she believes that you were transformed into a full, Greater Demon and demands her transformation, too.
* However, Lyssieth
has not changed you. (And Lysseith probably *just* finished telling you she
doesn't want to change anyone!)
* The game now
removes any method for *you* to fully become a demon.
* After any other NPC transformation(s)--
you still remain a part-demon.
* The game records 'part-demon' as parent race &
restricts the race of your children; you
can't beget full demon children.
* You
can't willfully shape-change yourself fully as other demons can!
If you need more info from me, please ask.
Thank you!
