      The bug

      When opening a map in an area that contains a spruce sign, jungle sign or dark oak sign, the game will crash. This occurs on both single player and multiplayer.

      Trying to enter the world crashes the game. If the player's held item is shifted away from the problematic map, the issue goes away. This can be done in multiplayer, by editing the NBT in the PLAYERUUID.dat playerdata file in the world/playerdata folder. In single player, by editing the NBT in the world level.dat file.

      This issue does not occur when using an oak or a birch sign.

      Also affects wall sign.

      To reproduce

      1. Place a minecraft:spruce_sign somewhere
      2. Look at a map of the area containing the Spruce Sign
        The game fatally crashes and returns to the Minecraft Launcher
