Hey there 

Whenever I go and chop down clovers or sometimes acorns at the moment the leaves/items drop down and immediately start vibrating on the ground in random directions it's honestly quite bizarre and I have no clue what could be causing it 

I do know exactly what you’re talking about. It’s a little frustrating but mostly it just looks weird. I think it’s just the game’s physics trying to have items roll and/or slide downhill but as these two item types or not spherical the code for the animations is still lacking. 

possible that the previous comment is correct with the roll, or its the hitboxes clipping with the group and those annoying dirt lumps that you can't build through causing it
