Jaheira picked up spell failure, i think at some point during the De'Arnise Keep quest. Since then I have not been able to remove it. I've been to the temple and have cast literally every spell they have on her several times and rested for days and still it sticks to her.
And no, i have not imported from Black Pits as i know this can cause this bug. (ive never even started BP before) The game is however heavily modded. All the mods though are off of the BG2 mod list on this forum and in the order suggested in the thread as well.
Is there a way to remove it using EE Keeper? I couldnt see anything obvious other then 2 "miscast magic " references under the Effects tab but removing these didnt seem to help either..
