Use Item can duplicate blocks by placing them

[wompking]

What it says on the tin. In Hexal version 1.19.2—0.2.19, it seems that motes don't decrement their item counts when passed to the Use Item On spell. This happens in Survival as well as Creative mode.

Steps to reproduce:

• Mediafy an item that can be placed in the world (like a block)
• Duplicate the mote with Gemini (to have a second reference to it)
• Put a block location and a normal vector on the stack (I used [0,1,0] as the normal vector)
• Cast Use Item On
• The second mote reference doesn't decrement its count, as it should, but the block still gets placed.

Here's a list of mods I also have installed that might be interfering.
