Paizo's website went through a rather rough patch for a while there. It seems as though the gnomes and sprites that keep all the 1s and 0s in order went on an extended holiday. Thankfully, they're back, and with them there's a new update for the Pathfinder playtest, including the next part of the ongoing adventure for you to try.
From the post:
Time flies when you're playtesting a new version of Pathfinder. It's been over three weeks since we got underway by encouraging everyone to play Part 1 of Doomsday Dawn. And play you did! The outpouring of survey responses from those who completed "The Lost Star" (Part 1) has truly been overwhelming. We've learned a lot about the game, but there's still so much to explore! That is why, today, we're moving our focus to Part 2 of Doomsday Dawn, titled "In Pale Mountain's Shadow."
Before we move on, I want to stress that while we're shifting focus to Part 2, it's still not too late for you to contribute to the surveys for Part 1 (which you can find links to at pathfinderplaytest.com). We'll be keeping those surveys open until the end of the year, and the results will be checked regularly as we continue to analyze the data.
