chevalier des Trois-Tours

I have a problem. I've done a book for someone and everything works smoothly except for the equipping effects selected: +1 wis +2 int.

When it hadn't worked and everything I tried failed, I even copied the effect directly from other 100% working Bioware items and it still didn't work. All the data entered are obviously the same except for which stat to change and how much. I don't see any possible reason for it not to function properly. There are no additional effects to interfere with. I've been doing various customs for some time, but I've nevered experience such a thing.

I hope someone knows the case, but should you wish to look at it and try it yourself I'll send it to you via email.

I'll be most thankful for any help.

Last time I read some 2ed extension and 3ed standard manuals, I got struck with an idea of making prestige classes for BG2 with ToB installed. The only trouble is to add the prestige class features without unintentionally worsening or removing any parameter/ability already had. Aha, and 'remembering' the initial class. Anyone tried that already?
