Wizpig Castle bugs?

Hey guys, I’ve already beaten it, but something doesn’t seem quite right, especially during phase 1. During the fight I used the Samurai to shield everyone 40-50%. The zombies attack seems to be negated by this, but when Wizpig uses his ability to let his target attack again, it doesn’t negate it and actually increased the damage from 100-200. (Wizpig’s abilities don’t say they give increased damage, and he doesn’t get more power as the Chilie meter fills, so it has to be a mistake/bug). Same goes for Phase 2 when he unleashes is 600 dmg attack. It hasn’t been getting mitigated by my Samurai ability. It’s making it pretty tough to survive during replays. Anyone else experiencing this?
