Unable to pick up item

Hi

I just defeated the Labyrinth map boss. He dropped several items including 2 maps.
I was able to loot everything except a level 73 map (Dry Peninsula).
Reentering the map and relogging didn't help.

Bug report reference number: 1206474422, screenshot below.



edit: I can still attack either the dead boss or the dead devour on top of it. Mana leech applies



I used vaal detonate dead and the corpses exploded. I was then able to pick up the map.
