Bug: Modding a Pretender, and when I try to create...

[Phoenixblood]

Right, I am modding in an Oni pretender for EA Yomi, the details are yet to be finalised but right now the code looks like this:

#newmonster 2001
#copyspr 1316
#name "Dai Oni Lord"
#descr "The Dai Oni Lord is the mightiest of the demon kings. Like the Dai Oni, he is huge and commands vast magical powers, though like all Oni, he is a terrible researcher. Like all Oni, he can adopt a weaker spirit form when defeated in battle, this spirit form must also be defeated to fully kill the Lord. The lesser Oni and their servants revere him as a god, and with the old Pantokrator gone, is out to become a true god."

and when I go to create a Pretender in game, my Dai Oni Lord is there, and right clicking the chassis in form selection displays the correct magic paths, HOWEVER, when I select the form and go to purchase extra/improve magic paths, I have an S1 pick out of NOWHERE, any idea how to stop this from happening?
