Choice of Magics — Your magic can change the world, but at what cost?

I have a feeling I found bug. If you not friendly with Tal during 2 chapter’s party you have option to glamor yourself. After that we have following code:

*temp talFriendly false
*if (tal_rel >= 50) or glamor_up
  *set talFriendly true

Now, problem is that glamor choice lack *set glamor_up true, so I think it effectively don’t work as intended:

#Yes, and to help things along, I cast a glamor first. 
You hide in an alleyway and cast a glamor on yourself, pulling energy from within yourself to create the slight golden aura.
 *gosub bump "glamor" 1 
You grab a nearby torch so that it isn't as obvious you're slightly glowing, and head over to Tal.

As you can see, it only bumps your glamor stat.
