Grim Feast: Remnants despawn

I have found a few forum posts around skill Grim Feast not overflowing your shield to twice your base when picking up the remnants, as I have been experiencing as well. I think this is potentially due to a despawn timer. I have noticed a similar effect when several seconds has passed before I pick up the remnant.

Hopefully this is a bug in the players favor and it is just not awarding the shield energy when it should, but if this is intentional and the remnants only last for a few seconds then you need to remove the sprites when they expire so we don't path around the map to try and pick them up (and update the skill text)
