The World of Avlis

I was playing with Time Stop the other night and noticed NPCs drinking Heal potions during the middle of it. That seems really, really wrong to me (seeing I was intent on their dying and they came out of the time stop barely injured).

Bug?

Misunderstanding of the spell?

Bioware Bug is how I've always seen it, the same way that they can drink potions while knocked down (but you can't when it happens to you).

Thanks Grunt. And I assume it's hardcoded rather than fixable. Ce la vie.
