Bug with constant "electric" effect of some spell.
I ran into some nymphs or sirens on one of the Sword Coast maps. I do not know the exact spell that started it, the battle was quite confusing. But after the battle, my party was constantly going around getting "shocked" like the spell still has effect. It looks like an electrical aura accompanied by a sound effect of crackling electricty. It happens again every time I save, sing a bard song, move to a new location or simply at random intervals. It is very annoying. I supposed it will wear off, but it doesnt. Is there any way to make it stop? Unfortunately I have no previous save before I realized this might be a bug.
