There's a bit of an error after choosing your weapon. If you choose staff, the next page will say "they set the hilt of your sword in your waiting hand." This happens whether you choose to trust Yezda or not. However, if you chose not to trust Yezda, the following line will say "as you secure your staff," so it seems that it's properly logging your choice, and it's just that one line that doesn't update.
Later on, when fighting the third warrik outside "the ruins of your old city," it'll say "your grip on your bow steadies" after choosing to "lunge beneath it" or "stand your ground." In addition, if you choose to stand your ground, it'll also say "you throw your body behind your blade" and "you wrench your blade clear."
