my tool/candle just appears on the floor where the model is when you equip it. your supposed to get it in your inventory when you click it but when you click it and equip it pops up inside the actual model that you clicked on to get it.
This behavior happens due to parts in the tool not being welded to the handle, or being anchored.
You need to weld all the parts of the model to the handle, and make sure nothing in the model is anchored
