Just deleted chain data and only have the main seed in conf, just going to see what happens on sync an il post the results in case it can help
Just tried that. It syncs with the superseed to a point, then drops it and starts syncing from one the forks.
I think it needs to be hardcoded so the clients will ONLY sync from the superseed at the moment. The full network functionality can be restored later once we have a single solid chain. I don't know if that can even work... I haven't looked at the code. It's the only idea I've got though.
