Items not showing up when dropped

[Marmalade]

I'm making a mod that adds a new item and tools made from that item. When I play the game, the item and tools are find when in my inventory, but when I drop the item or any of the tools on the ground, and when i'm holding any of the tools their invisible.

Some items have different textures whether they're on the ground, in your hand, or in your inventory.  Have you assigned an inventory image, and none of the others?  (Someone may want to fact check me on this.)

I've assigned an inventory, and the items all have an anim file. They just won't show up in-game

Does that animation file contain images for the item being on the ground, similar to how a shovel on the ground looks like it’s in the ground?

Yes, that and all of it's sprites when it's being held and used to dig.
