Can't plant/drag in planter boxes

I have created a new save, only to find that another rendition of the gardening bug has returned. I cannot drag plants from my sim's inventory to manually place in planter boxes, nor will she plant them herself. My sim will walk over to the planter box to complete the action. The animation of her placing the plant will run, and then she will 'glitch' back to default standing, and there will be no plant in the box. 

Unsure if this has already been posted.

NOTE: I can drag all other items from the sim's inventory, but I cannot place plants on the ground or in planter boxes.
