For minecraft 1.7.2 release 1.5, I was playing with HEE with a freind and we went to battle the ender dragon and after 5 to 10 minutes, We crashed!! We went back on the server and the ender dragon totally disappeared. Another thing is when me and my friend go to battle the mini bosses, My friend lost connection on my server and whenever he tried to get back on, he would automatically disconnect until I defeated the bosses.
