"minor magical effects" spells bypass saves

Hello, I noticed "minor magical effects may be found in your travels" (baffle, unnerve, etc) will ALWAYS affect you if you use potion/scroll/wand containing one of them. To illustrate: You recite a scroll of fear. (on Sharasen) Sharasen clutches at his head briefly, but his focus returns. (he resisted) You recite a scroll of fear. (on myself) A clatter of voices fills your head, and your concentration begins to slip. (I NEVER resist) //I suspect these "effects" are marked as beneficial spells for some reason. And saving throw is bypassed.
