*What I expected to happen was: i could place a sign on a sign
i could place a sign on a sign
What actually happened was...:
i just can't
Steps to Reproduce:
1.place a sign on a wall
2.place a sign on the sign you just placed
(i'm sorry for bad grammar i am dutch)
You have to hold "SHIFT" while clicking on the sign, else the game thinks you want to run a command which is stored in the sign (JSON was added to signs too)
