Nether was reset anyway because the map destroyed itself, and I believe there was no backup. A few players on Ventrilo actually said they can't seem to find some spawners, and one person who did find one said It was outside the border of Ecocitycraft's nether extension. However, I'm sure you'll be able to find more spawners. Anyway nether was due for a reset soon anyway. This merely sped up the process. Since the last nether reset was a few weeks overdue, this could have actually put the nether schedule back on track. I wish you all good luck in finding another spawner and hopefully it won't get nuked. Happy searching
I've already found 8 and I stopped looking when I found the perfect pair. They are out there you just have to look.
