Idk if this happens on normal survival worlds as well, but in the server I am a part of it is happening a LOT. Every time I go through an end or nether portal, I am temporarily falling through the world, and I lose my items. It returns back to normal in a few seconds, but this time it did not. This time it lasted for a solid TEN SECONDS and I was kinda scared that I was stuck there forever, because it had never lasted this long before. Please fix this issue, because it is getting scary for me, because at one point I just might be stuck forever.
