Looting Table Disappearing

So im running Haramel and when looting the raw/fine odium to get my quest items i click "C" to pick it up but it just closed the loot window and then it disappeared. i cant get my quest done ;-; no worries tho just letting u all know! Thanks!

looting with your attack button wasn't a thing until later patches. i believe 4.0 is when that started, you may want to get into the habit of pressing take all for quest items in this version.

This is a version-related thing, at that time items that you collect from a container disappear if you abandon them.

The same goes for treasure boxes, which contain relics.
