Ender portal incomplete

Please provide seed and coordinates.

I have update the post with coordinate and seed

I was not able to reproduce your problem. But I did notice that area around the End Portal was different depending on how I arrived. I created a game in creative mode, waited in the spawn area to let the initial chunks load and then teleported to the coordinate you listed. Everything with the End Portal and room seemed normal. There is a "cavern" somewhat intersecting with the hallway outside the End Portal room. Next I started a survival game and traveled there by foot and dug down. In this game there was lava spilling into the hallway leading to the End Portal room. I went back to the first game and broke through the hallway wall and saw pools of lava close, but not that close by.

Cannot reproduce either.
