There's definitely something weird going on with bow attacks missing more than they should. I had Sebille miss 10+ attacks at 94%+ each in a row across multiple fights, and she only started hitting again once I saved and reloaded. This scenario repeated itself a couple times throughout my most recent playthrough. Something's getting stuck and not working right occasionally in the inner working of the to-hit rolls, or I need to start buying a lot of lottery tickets.
It's a blind bug. Blind -Accuracy effect lingers even after fight already ends until you save and reload to get rid of it.
And it's pretty much forced to because you can't even attack knocked down or CC'd target with it.
