I entered the Nether, left within one minute, and when I tried to the doors to my house, which were maybe a hundred blocks away, only the top half or bottom half would open. If I tried to close the open half, the closed half would open and vice versa. I reloaded my world and it fixed the issue. I went into the Nether again a few days later (irl and in-game days) and had the same issue when I returned to the over-world. This was all in single-player.

Nothing game-breaking, just inconvenient. I attached a screenshot (cropped) of the problems I had with the doors. Excuse the texture pack.
