We were fighting in the mines, and after my brother activated his PB, the Garanz missiles still hit me and downed me (TY @Spuz for the Scapedoll), even though everything else was completely blocked in animation. Is it normal?
This happened because you used PB inbetween waves. Enemies have to be fully spawned in for them to stop, even then I don't think all projectiles stop so its best to be careful and keep mindful of this.
