Gearbox should fix that cuz it is a big problem. I have been farming for a skull masher for a while with sal and when I finally get one I get a 48 to drop. I was so pi$$ed off at the game I stopped playing it for a few weeks.
You should just be happy it didn't fall through the floor.
Just this morning I did a few Southpaw Steam & Power runs, and on one, I just killed the second assassin, I saw he dropped an orange, likely an emperor, I was just about to pick it up when another suicide psycho came of of nowhere and blew up, and as I watched in horror the explosion pushed all the loot over the edge into oblivion.
I didn't really need the Emperor, but still its aggravating that this is possible.
