Items spawned where they can't be picked up

This happened in an Arsenal map, indoors, within warehouse layout. Screenshot with bug reference number attached.

Was mapping - killed boss, a unique Crypt map dropped right on a stalactite and it will not let me pick the item up. I tried to get as close as possible and grab it but did not have any luck.

Next time that happens, the first thing to try is turning loot off, then back on (I don't know the default key set, but I *think* it is Z. So, double tap Z, to hide all loot, then display loot tags again. This will reset their location, in case the tag is too far off from the location of the actual item, has been pushed way off because too many tags had to fit in a small area, etc.).

This doesn't always work, but I find that it does quite often.
