The mini dashboard is located to the right of the pool page under "My Stats". Enter your wallet address there and you'll also get a link to a more complete dashboard.

At some point we had like 10% of the global hashrate and then they left. Must have been an entire farm.

You are or have been mining erroneously using a worker name as Monero Payment Id. I've manually fixed your balance but unless you fix your config and replace # with a dot, it will happen again.

Additionally the network difficulty has increased by more than 30% since the last block was found.

Can I have your address? I'm currently hard at work figuring out whats going on. This is clearly just a display problem but it absolutely needs to be fixed.

I think all is fine on your end. Still remains a mystery to me why your reported hashrate is much lower but I won't give up until I've figured it out.

Should be fixed now. Monacoin daemon also had a problem that didn't manifest itself until after the daemon got restarted.

After a second inspection a problem with the vertcoin daemon surfaced. I'm currently trying to fix it without a full resync. Will keep you posted.

I've checked everything but the pool is doing fine.

I've just tested it. My hashrate is a bit on the high side but definitely not lower than reported locally (using a single GTX 1060):
