Dear Dead In Vinland Development team

I like your game, but the fight against the Sword Wielding Woman is simply stupid.
WHY do you cancel out all my Buffs without ANY WARNING or information???

The fight starts, and all the carefully crafted Buffs are GONE.... only the penalties remain.

What is the point in buffing, and levelling for the fight if it is just cancelled with no explanation?!?

This point is enraging!!!
