15h after release:

dev:
"...Its obviously not working. The reasons could include:

• No supermajority on the latest version
• Bad upcoming superblock due to proj avg being out of range, proj count divided by whitelist count, or avg Magnitude
• Md5 hash differences in the source files over the nodes
• Quorum Hash Algorithm region problems
• etc

I realize this is painful and we (the devs) apologize for the pain. We will take this up again in the dev (slack) chatroom and see whats going on. I think we will need to actually mock up a fake superblock in testnet and try to force it in testnet with more logging, to see what is being rejected."
