Remember the pack is collection of various mods, from various authors, every each one of them is responsible for own mod, sometimes they may create unpredicted results. I cannot test every mod combo, because I would need to have to clone myself for that.
Noticed you are using "Multi Hit Log - InBattle WN8, EFF, Damage". I saw some report on russian forums, where they was saying that this mod may lower your FPS significally after few hours of playing. Try to pull it down.
