My world that I created after the latest update seems to be completely missing Nether Fortresses. I know it's possible for a world to generate without one, but that's never happened to me before in the dozens of worlds I've played on. I went into creative and flew around to double check but could not find a single fortress. Oddly enough though, I did find Wither skeletons clustered on a patch of Netherrack. My understanding is that they only spawn inside the bounding box of a fortress. I did explore that area pretty thoroughly, digging down and such, but there's definitely no fortress there.
Checking the official bug listing, I've not seen this particular issue listed yet. Has anyone else ran into this, and if so, is there a way to fix it?
I can deal with some bugs, but this one is pretty much a game breaker for me.
PS. Sorry, I just realized I posted this in the Xbone section and i'm on a 360.
x129 y56 z91, this a relatively safe place to dig to. The fortress is tiny consisting of only one lava pool room two straight walkways, a crossroads and two blaze spawners. It is almost completely buried in netherrack, with only the pillars being visible from the lava lake below. If you build a portal at world spawn you will be close to it.
