Why does this say that "Position is not a valid member of model"?
local Spawns = game.ServerStorage.DFPos:GetChildren()
local Spawn = Spawns[math.random(1,#Spawns)]
local Items = game.ServerStorage.Zoan:GetChildren()
local Item = Items[math.random(1,#Items)]
local Clone = Item:Clone()
Clone.Parent = game.Workspace
print("Df spawn")
Clone.Position = Spawn.Position
wait(1)
Clone.Anchored = false
game.Debris:AddItem(Clone, 30)

Are the children of DFPos spawnlocations or models? models do not have a position property.
They are parts. So it gets their position
Are children on 'Zoan' parts too?
If either Zoan or DFPos contain any Model objects, this can error.
