Is “Handle” a Part with it’s .Shape set to Ball? If so, it’s possible that Roblox considers the shape of the sphere differently depending on whether it’s in a humanoid (sometimes they do weird stuff to rendering). To fix this, make sure the .Size of the Part is 2x2x2 and not something that gets visually rounded to 2x2x2 normally (ex: not something like 4x2x2). (TL;DR: might be a bug from this update.)
You could add these statements to debug:
print(game.ReplicatedStorage.SushiMaker.RiceSphere.Handle.Size)
print(rice.Handle.Size)
after this line:
local rice = ...
