help with newbie modding

[JPSeraph]

Okay, rather than start a new thread, I'll just ask here:

I tweaked around with the Knights of the Stone and after running about 300 turns in a test game (with luck 3, turmoil 3), I have Bernlad, Rhianne and Brangwen, but no Knight of the Stone.

Is there any way of knowing if I accidently messed something up? There were no error messages and everything else I modded seems to be working just fine.

For those who might want to see the changes, here goes:
#selectmonster 58
#ap 30
#mapmove 3
#hp 20
#str 14
#att 18
#def 17
#mr 15
#mor 18
#heal
#reinvigoration 3
#standard 20
#weapon 330
#weapon 998
#armor "Mithril Mail"
#armor "Mithril Helmet"
#armor "Mithril Kite Shield"
#end

The Mithril armor all seems good to go based on other armor I have created which did work, same with the #998 weapon.

The #330 weapon is "Alicorn". I was trying to switch the mount from a regular horse to an Alicorn. Could this be the problem?

Any insight would be greatly appreciated. Thanks in advance!
