I am having a problem testing my mod.

I created a new spell and a spellbook for it. It is an Expert Alteration spell.

I added the spellbook to one of the Leveled Lists sold by Tolfdir (LItemSpellTomes75AllAlteration). I then loaded my test character, and moved Tolfdir to him. I opened Tolfdir's shop inventory, but he was only selling Novice- and Apprentice-level books.

I then used console command player.setav Alteration 100. Now my alteration skill is 100. I waited 48 hours, and opened Tolfdir's shop inventory again. But he still wouldn't sell Adept and Expert books to me.

Funnily enough, if I used setstage MGRitual05 200 (complete Alteration Ritual Quest), in 48 hours Tolfdir started selling Master Alteration books. But still he does not sell Adept and Expert books.

What gives? I'm 100% sure there are no mod conflicts.

Help appreciated.

Have a look at the scripts in the MGRitual05 Quest.

My guess is that somewhere around there (in it, or in a related alias-script, or something similar) there is a scripted-change to the ACTIIVE levelled-list of the spell-books Tolfdir sells.

(As in he starts selling "GimpedList" and - after that quest is complete - switches to "NotGimpedList")

?

If that's indeed the case, is there a quest somewhere that manipulates the availability of Adept and Expert books from College vendors? Because I can't find one for sure.

Vendor lists work off your level, not any individual skill.

Not sure about that, I tried setlevel 50 and no change.

However, when I used "advskill #####" command and advanced my skills that way to appropriate levels, the spellbook appeared. So I guess that's the right way to proceed.

Story Manager has a "Level Up", (or something very similar) event.

Have you looked at the Nodes under that event to see if one is "unlocking things" when skillUp happens?

I don't see why setLevel and Advskill produce different results unless the latter is somehow being picked up as an event, but the former is not.

Check it out?

When the player's skill advances (and only when it increases naturally), a global value is changed to 0. Simply set that global to 0 and let his vendor list reset to buy your new book.
