I can confirm, Ampz does not appear for me.
Launcher version: 1.2.4
Java: 7u21 (64-bit)
OS: Windows 7 Home Premium (64-bit)
Console finishes loading packs, moves on to maps and texture packs and completes those as well.
Different download locations do nothing that I can see, although I may be wrong with that. I tried with Chicago 2, England 1 and Scranton 1.
Console does show this mid-way through loading packs:
Code:
Can't get input stream from URL!: javax.imageio.IIOException: Can't get input stream from URL!
Maybe it's having trouble getting that one pack's info from the server for some reason? Could be the download location only changes when downloading the actual pack, not just the info for the packs?
