What issues?
Maybe i can help, if problems with network code.
Wish I knew the details, I'm mostly the conveyor though (call me the bearer of bad news in this case), and I don't thing the programmers would want me to set up any help for them

Will it be possible to mine it with nicehash as well?
It is Equihash coin, Nicehash mines whatever buyers want it, so...
If you sell hashpower - it doesn't matter, as they will probably min it, and you will get pay

If you buy hashpower - yup, the moment there is a pool onlne you can mine it there, same as any algo available in NH.
