What's the difference between what I apparently have on now and area loot?

I don't know if anyone else is having issues or hasn't noticed, but it seems like the new patch is preventing me from obtaining almost 80% of all loot that becomes available from fallen enemies. I've noticed that as soon as I select a body to loot, all the other bodies with loot become "loot-less." I don't know if that was intened in the patch or is a bug, but I would like to know any or all information on the issue. Thank you.
