[A13] Farming on Trees, YAY! (But unintentional...)

[Yncensus]

Summary:
Somehow my crop grew ON the tree, instead of on the ground…
Steps to reproduce:

1. Promote a farmer, grow some tree saplings.
2. Place a crop.
3. Place a tree sapling directly beneath the crop, so that the tree’s crown is above the crop.

Expected Results:
The crop should grow on the tilled ground as usual.
Actual Results:
The crop grows on top of the tree.
Notes:
Likely connected to a previous noted bug, listed here (farming on lowest y-plane).
