Foxes won't pick up tools and weapons

Foxes can't seem to pick up weapons, armor, or tools, even if it's the only thing on the ground but will pick up everything else like normal.

1. Load up a creative world and spawn some Foxes
2. Throw some armor and weapons on the ground
3. Throw some blocks or random items on the ground

They will always go for the normal blocks and items, but never the weapons, tools or armor
