Thanks for the informative post. Unfortunately, we're still forking. As I write, I'm on my second fork since installing 3.7.7.0. Three of gridcoinstat's servers are on the same fork. To fix this, I've been advocating disconnecting nodes running old versions after a grace period and having the wallet push upgrade notifications. I say this because the problem appears to be coming from nodes running old versions. One of my peers is still running 3.6.3.0!
