I want to "fix" my nether fortresses, but a can't seem to find the standalone .jar file. All Mojang has given is the server version. I'll grumble through a reinstall if I have to, but does anyone know how to get this up and running/where to find it?
I don't know if this answers your question, but you select 1.6.3 by editing a profile, enabling the use of Snapshots, and selecting 1.6.3 from the Snapshot dropdown menu, as if you were enabling a 1.7 image. Do not select use latest, that will use the newest 1.7 'shot.
Ok, I found the option. I cant decide if the way they did it was usefull, or obtuse...
It may seem obtuse, but as it's currently a pre-release and not an actual update where do you expect to find it? Judging by the lack of re-uploads of the 1.6.3 pre-release I think it'll be out Thursday anyway, so you could've just waited if you didn't want the hassle.
