I have this problem but it only seems to be with one specific portal. It happens to be one rebuilt where a broken nether portal spawned. My friend has an iffy wifi connection that I suspected was contributing to the problem. He falls right through the world until his character times out.
I've also noticed that I (Client on Host PC) experience some "drops" when I use the portal. As in, I hear myself hit the ground twice, as if I'm spawning in the air.
I tried clearing blocks around the portal, re-lighting the portal. No difference. All other portals seem safe, but this one is weird even for being on the same PC.
