'''Configuration:''' version: 2.5 / system: AMD64 / GPU: RV790 / module: "ATI Radeon HD4870 and earlier"

'''Game-play impact:''' none
'''Reproducibility:''' triggered at will (on two maps).

'''Description:'''

Usually, you never try and drop an item when you know that a soldier's TUs are spent. Still, it may accidentally occur.
If you do so (when I do so), you most likely trigger the following graphical artifact:

'''a white octahedron''' (like 8-side dice) '''appears at soldier's coordinates''', circa at belly height (when crouched, this mean circa shoulder height).

'''First conclusions:'''

As far as I can tell:
* the artifact is created on the very turn the item is "not dropped";
* it's static (save for a slight texture effect);
* the soldier doesn't have to be crouched;
* it remains on the spot when the character moves;
* it lasts several turns, if not until the mission ends;
* several ones may be created on the same turn by following the same procedure as described above (with several soldiers of course);
* sometimes, the artifact doesn't appear immediately (on closing the window), but "then", it's there (I have to be more precise!);
* smoke at soldier's position is not relevant, but there's always smoke on the map when I experienced and tested (I have to test again);
* '''dropping an item on the same spot cancels the artifact''' immediately (experienced on the next turn with the same soldier);

I didn't tested if
* "not enough TUs" is the only trigger (0,1 and 2 TUs are sure for the backpack)
* the place where the item is stored is relevant (backpack is sure);
* it only occurs with two slots items or any item (PRL ammo and laser ammo are sure);
