Whenever I load an infinity single player world the chunk generation is unplayably slow. Eventually the chunks will just stop loading altogether at a random point in the world and reloading and restarting won't make it load past that. I've reinstalled the pack and that makes no difference. Also /forge tps or other means of testing TPS usually returns after around 10 minutes a number <0.1 I can play on multiplayer servers with no such problem. I was also able to play this pack in the past with no problems on the same computer. Any Ideas would by appreciated.
