My friend who is the only person having this issue and reaching out to see if I can resolve it for him.
SO at first his client didn’t like a few mods from my modpack but I think this was more spec related than anything as everyone else is able to play fine and load. Now that he was able to load he get like 1-5FPS in main menu but once he is finally able to get to the mp section and join the server the game run fine 50-80fps.
However, randomly he will freeze and my server reports this as happening. On his end in FML log it doesn’t show anything as happening.

He is doing nothing specific and is random.
