In scripts/prefabs/veggies.lua, placers were added for each of the veggie seeds in the MakeVeggie function. However, they don't get added to the returned prefab table because only the first three return values are captured.
This is also an obstacle for Geometric Placement compatibility, as the placer prefab is missing.
Steps to Reproduce
Play as Wormwood, c_give("seeds"), c_give("carrot_seeds") -- seeds will have a placer, carrot_seeds wont.
