This happens mostly on infinite worlds

Mostly when I want to reach a far destination, (Let's say somewhere with a place that's 500 blocks away) in a short time, the world glitches sometimes and gives me a loading bar on the centre. I wasn't worried about because I think it'll load back in a short time. But the thing is that once the loading bar appears, it never goes away until you enter the world again. By the time it loads back, my progress which builds up around 5 mins before the loading bar pops up will be lost. This is even more critical when you enter a nether portal, the loading bar will stay there forever, risking the fact that the nether portal will be gone and getting stuck in the nether because the progress i built might be lost.

Please fix this because it's giving me a lot of inconvenience, thanks!
