An enemy stepping on devil vines will break your pacifism.
Burning bush, I get, but the main reason you're using devil vines in the first place is the parry. I've had people recommend 1pointing it, even, to minimize the damage it does do.

For the love of god, if EBV is allowed to maintain pacifism, let my vines do it too.

I don't think this is a bug because other field tiles will also break pacifism. Vengeance is treated as status damage, which is why it doesn't break Pacifist Boon.
