Seeds from Plants can Spawn on Top of Buildings

Summary:
Saw a berry bush seed lying on the roof of a building, possibly spawned after harvesting the berry bush that was placed near the building

Steps to reproduce:

  1. Get any plant that has seeds (preferably berry bushes) and place it very close to a building
  2. Harvest the plant for the seeds
  3. The seeds may spawn on top of the building instead on the ground

Expected Results:
Seeds on the ground

Actual Results:
Seeds on a roof

Notes:
The berry bushes were placed after the building was complete, meaning no hearthling holding the seed would have been able to get on the roof.
You can see in the screenshot that the berry basket spawned on the ground while the seed spawned on the building.

I used the autoharvester mod to harvest plants like these berry bushes.

I don’t know if you’ve noticed, but the actual seeds tend to spawn in mid-air and then drop. Likely, it spawned in the air above the building into the space around the bush and simply landed there.

I wonder if the design for them spawning was originally for falling out of trees, and then they expanded it to work for all wild plants and didn’t adjust where they were spawning.
