So earlier today I was playing on a server then I logged off for about three hours. I got back on and every time I tried to open any version of 1.8 it starts and then crashes. It says it has something to do with json. 1.7.10 and below open just fine. What should I do and is this normal?
1.8, 1.8.1, 1.8.2, and 1.8.3 won't open.
