Strange behavor of objects

Hello, sorry to post again, in my project i’m making the character drop the objects and if i make the rigidbody too small it go through the ground, but i already have a vary small object placed on the ground and don’t go through. Don’t know if anyone can help me understand why.

How can we recreate the issue? I just tried to drop the quiver but that errored and didn’t drop them

Edit: Ah I see, when you drop the sword it goes through the ground but when you drop the shield it does not

yes coz in the shield i have put a cube collision component, but if i make it too thin it goes through as well…if i use the mesh goes through… but if u go near the shoot field u see a potion on the ground and it doesn’t go through…i’m perplexed
