I notice that the OP mentions retargeting every block, but from my PoV the difficulty is changing every 1440 blocks.
In addition, the last 100 blocks have taken over 10 days to be minted...
So I am guessing that adding gravity well retargeting has caused a hard fork, and I'm stuck on a chain with older clients, but I can't see mention of any urgent updates in the OP.
Am I missing something?
