When both nodes spawn on top of each other, the other "node" sprite will disappear. 

Steps to reproduce:

1. Herb an area.
2. Node appears.
3. Scrounge an area.
4. Scrounge node appears in same spot, "deleting" the herb sprite.
5. Scrounge the node.
6. Herb sprite is still not there.
7. Scrounge the herb.
8. Herb acts as normal, but the spirte is still not there.

Note: Due to the variables in scrounging and herbalism I don't fully know if the node sprite will reappear. In the test I did it did not.
