I was trying to help set up a ladder when I saw my ladder-carrying ally fall in battle. I picked up his medium ladder, which made me drop my light lance. So, after setting up the ladder, I went back to pick up my lance. However, I was under enemy fire, so I panicked. So I accidentally pressed F twice on my lance, which dropped it again and gave me another ladder. Also, when I started using my lance again when I switched from the ladder (or something similar to that action), it gained blunt damage for its thrust.
