@Skylinerw It does indeed. Strange, because just earlier today i tried a book with only the title: Test, and the author: test. And it did show invalid book tag as well. Thanks nonetheless.

Here is one of the commands I'm using:

/give @p written_book 1 0 {title:"Admin Command Book",author:dragonmcmx,pages:["{text:\"  Admin Commands\n\n\",color:dark_red,bold:true,extra:[{text:\"Gamemode Creative\n\",color:gold,bold:false,hoverEvent:{action:show_text,value:\"Hop into Creative Mode.\"},clickEvent:{action:run_command,value:\"/gamemode 1\"}},{text:\"Gamemode Survival\n\",color:dark_gray,bold:false,hoverEvent:{action:show_text,value:\"Hop into Survival Mode.\"},clickEvent:{action:run_command,value:\"/gamemode 0\"}},{text:\"Toggle Downfall\n\",color:dark_blue,bold:false,hoverEvent:{action:show_text,value:\"Toggle Rain/Snow.\"},clickEvent:{action:run_command,value:\"/toggledownfall\"}},{text:\"Clear Lag\n\",color:dark_green,bold:false,hoverEvent:{action:show_text,value:\"Remove Ground Items.\"},clickEvent:{action:run_command,value:\"/kill @e[type=Item]\"}},{text:\"Time Night\n\",color:black,bold:false,hoverEvent:{action:show_text,value:\"Set the Time to Midnight.\"},clickEvent:{action:run_command,value:\"/time set 18000\"}},{text:\"Time Day\n\",color:blue,bold:false,hoverEvent:{action:show_text,value:\"Set the Time to Midday.\"},clickEvent:{action:run_command,value:\"/time set 6000\"}}]}"]}

Worked perfectly in 14w25b, broken in 14w26b and 14w26c.

@Skylinerw, I meet all those requirements and still get those errors. Even if i don't add any json data to the book, it still outputs * Invalid Book tag *.And the books did work perfectly in 14w25b, so yeah.

Nothing to do with recource pack. I've got the same bug in vanilla minecraft.

I've got the same problem. Any books with json data just output: * Invalid Book tag *
