problem

I've been having this problem recently, I've been trying to make a Book, but every time I write more than 3 pages on a book, it kicks me out of the server? I cant figure out what happened, I tried having more paper, but it doesn't work.

Pistons placed in double extending position use the standard 2 tick, 4 tick, and 0 tick formation to work but now, in the past day or so, there is a glitch that doesn't allow this system to work. If this could be resolved, that would be much appreciated by everyone on the server. Thank you.
