After my fusion gun fired, there were some strange legacies.
Instead of ammunition sleeves, there are some “none”-items.
And I can’t find the id for plasma-remains.
If you’ve picked up some none, it’s only possible to drop it with the advanced inventory managment.
On a barely related note, I’ve noticed that you can’t shoot through vehicle tiles with guns. Seems everything’s treated as being solid even though you can see through it. Haven’t done any extensive testing so I may very well be overlooking something…
