Ok I have been trying really hard to get minecraft modded and working. I finally got it done today but everytime I try to open a world it would load and I get 5 min to play, and it would say shutting down internal server and crash. I dont understand why thing happens but if someone could help me that would be amazing.



This is the report it is giving me.
