I am playing on a ssp world and it doesnt have cheats. I found out that starting a Lan world with cheats allows me to use cheats, but now, whenever I start a LAN world with cheats, and enter any command such as /gamemode or /give or something else my game crashes! IT never did this before I made a fresh copy of minecraft. Does anyone else have this problem? How can I fix it? Also, im not able to join servers, either I start joining and it freezes or I log in but fall through the world and cant use chat? Thanks for reading this! Also, heres the error for the single player problem:
