Okay, so I'm doing the final mission of the game (I'm assuming) where you infiltrate Rome to assassinate Borgia. During a fight with the wall guards, I stole a seeker's spear and killed him, and a brute with it, ending the fight. So, I pressed the B button to drop the spear, but what ended up happening was Ezio dropped the spear AND my equipped sword (Sword of Altair) and picked up a nearby sword, with a little notice below my health bar saying "Weapon Swapped". I try to pick up my blade, but it only puts it as a temporary weapon. How do I replace the sword I just picked up with my original blade?
