So basically, I was on my way home after exploring an end city (with a boat, so I had just gotten my first elytra) and when I teleported through the portal back to the main island something weird happened. For some reson, even though there were blocks aound the other side, it teleported me where there were no blocks underneath and I fell to my death. This bug could mean a lot of rage quits from worlds, which I was, and still kind of am, considering. So please, it would mean a lot to people if you could fix this problem.
