Hey, I have an issue on my hardcore world. I just killed the ender dragon and I was exploring the outer islands (1.15.2) but I just tried to go back on it and when I rejoined the world its like there is nothing but void around me, I cant use my items, I cant move its just a void area, is there anyway to fix this? Thanks

edit it seems to have fixed itself now, im not sure how to close it so i just thought id write it here.
