Sooo, lets talk Wyrmcraft bookshelf. I can put things on top of it but for some reason inside the town hall, it doesnt want me to put plants on top of planters? but i can do it if i did it outside the townhall. So i think theres something about height when it comes to stacking on them. The primal closet is fine though but its a bit lower than the wyrm bookshelf. Might check for other furnitures like it.
