Overworld doesn't load when coming back from Nether

 In one of my survival worlds ** it happens almost always when I'm coming back from Nether, that the overworld doesn't load. I just jump into the portal in nether and the loading screen keeps on loading and loading and loading until I have to reset whole game. Only in really rare cases happens that I come back from Nether without reseting the game. I found out that when I play this world with any of my friends, this problem happens less but it still sometimes happen. Please fix it, It's impossible for me to get back from nether.
