Co-op vs AI katarina bug PLUS poacher's dirk bug

I have no pictures, but the Katarina AI bot in the intermediate bots doesn't have a keystone and in the loading screen, her keystone box image is that bright blue instead.

Poacher's dirk, when it upgrades into serrated dirk, used up a long sword I had in my inventory and made it disappear, presumably since the serrated dirk calls for two long swords in its recipe.
