If you have the Placeable Sell Points by Loki_79 that may be the issue as it was preventing the tree planter from actually planting saplings. He just came out with an update last Thursday that fixes it. So you may need to update that.

I made the Placeable Pillow mainly for console player and those who enjoy a little role-play. It is a sleep trigger that you can pick up and move anywhere on the map after first placing it.
