I know this is a common bug, but I've been searching for solutions for this problem for several days now, and have had no luck. I want to play singleplayer properly but cannot due to this irritatingly consistent bug (happening every time I log back into a world). I have Forge downloaded, but don't use it when playing singleplayer - is having Forge a factor of my difficulties? Days earlier, I found that naming worlds exactly the same can cause this problem, and decided it was the reason, but chunks are still moving in my new worlds, named differently. Help.
