I kinda have to agree on that one. Well, I didn't mind it much until just a few hours ago actually.
Basically, this is what happened: (SPOILER)There was one on a bridge. I managed to kill it. The loot fell right through the bridge. There was ground below, and I just barely survived the jump... and right before I could pick up the loot, I was attacked by a foe I hadn't seen from the bridge and I died, losing out on the lizard's loot forever. =(
