Unfortunately the parity wallet (last version) that we used on the pool.sexy is not compatible with the fork, this lead the pool on a wrong chain.
We recognised the problem and changed our wallet to gexp and we brought the pool on the right chain, we also informed the parity development team about the problem (please dev team see: https://github.com/paritytech/parity/issues/7061 For network security it is good to have two different wallets)
During the mining on the wrong chain the pool found 2 blocks and sent 9 payments.
Even tough we did not receive valid coins from those blocks, we decided to use our founds to refund users using our previous gains.
Good mining
Because you are stand up guys, send me a pm and ill send you a few coins to cover your outage.
