I'm not sure if it's related to the other recent woes, but the only block explorer I'm aware of for SexCoin last saw an SXC block four days ago.
https://chainz.cryptoid.info/sxc/ perhaps with a lack of exchanges, those merge mining sexcoin have turned their miners to DOGE coin which jumped eight-fold a little over four days ago.
No one mining = No block chain = trouble.
You don't need to stop merge-mining SXC to merge-mine DOGE. Many pools merge mine several auxpow coins. As long as they have different chainid's this will work just fine.
My last SXC block was mined today and has currently 280 confirmations, so cryptoid's BE probably just stopped updating, but SXC chain is moving forward smoothly.
Their current height is 4171178, my height with 8 connections is 4177088, that is cryptoid is stuck since ~5910 blocks as of now.
May I leave it to you or the person paying for cryptoid to inform them?
