Ok https://sloth.crunchharder.net fully up and running again - not much SLOTH lost (and what there was I have covered from my own wallet to ensure no miners lose payments). I did discover (when checking my own wallet here) a SlothCoind - so the old code was building as SlothCoind and the new as Slothcoind so when I copied the new binary to /usr/local/bin on the pool server expecting it to overwrite the old one, I ended up with two instead and must have started the old one again.

One thing Thimo - I've only got one connection to the network from the pool wallet, and the same on my own wallet at home - I'm guessing the seed nodes are overloaded, might be an idea to rebuild the Windows wallet with UPNP if it's not already and see if you can increase the maxconnections= on the seed nodes.

Thanks again to Thimo for the help and support, and sorry to anyone who mined with CrunchHarder during the fork.
