Minecraft Username: Joliver1998. Brief Description: Building a bridge, I put the sign under a 3x1 wood row and another on the other side. Sometimes it will stay, sometimes it will pop off. Me and Mardigan_The_Mad worked for about half an hour trying to figure how to get it to work. Instructions: 1: Place a 3 wide wood row one block above the ground. 2: Put a sign under the middle block on one row and put [Bridge] on the second line. And that's it for the sign. 2 1/2: If it pops off, theres the bug, you can try for several more times and possibly get it to work doing the exact same thing over and over. 3: If it doesn't pop off, redo it and odds are it will pop off. How many times did you recreate this bug?: Several times. We only got the [Bridge] sign to stay in place a few times. Result: The bridge sign pops off and doesn't stay. Expected Result: The bridge sign to stay, and use to toggle a bridge. Evidence: It's hard to take screenshots of it. It just pops off, like breaking a block.
