Perk named "Spatial Manipulation" (items dropped when mining or slaying monsters are directly transferred to your invertory) places items directly in invertory, but not to the dunk/null when it's possible.
Hello MrILL This is because Astral is circumventing the normal inventory pickup code and just placing it in your inventory. Dan/nul doesn't even know you picked something up. Unfortunately, that means there isn't anything we can do about it. The AS dev's would need to adjust how this perk works and that's unlikely. HanoverFist69
