I am also experiencing this issue in Single Player in release 1.12 on Linux 4.9.16 using 64 bit OpenJDK 1.8.0_121 (IcedTea 3.3.0). I have entered one End City without a ship that would have generated before I got 'The End... Again...' and another with a ship that would not have been generated yet but, not got the advancement. The world was generated in 1.12. I can provide more info if necessary. Full output of java -version:
openjdk version "1.8.0_121" OpenJDK Runtime Environment (IcedTea 3.3.0) (Gentoo icedtea-3.3.0) OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)
Edit: I eventually got the achievement when I went into another End City recently, a couple of months later. It is possible that the one I entered that gave me the achievement had generated first, depending on where it falls in regions. It was through a different End Island Portal that I hadn't began exploring yet, so it may be to do with one being generated, you going through a portal back to the central End island, going through another, and then not being able to get it?
