Steps to reproduce:
- Plant a tree.
- Plant another tree within the same space.
- Wait until trees have been planted.
One tree would be planted, then the second would give an error/be canceled.
The first tree was planted, then the second was placed on top of it.
This can happen more than once, (a third tree can be planted on top of the second one.)
