He's gone to bed for the night, but I will hit him up first thing in the morning. Sorry for the inconvenience!
Maybe i can help about the error, do you know what coin Nadircoin was forked from? That will help finding how solve the "block not start with coinbase"

Oh, that would be great!
It was forked from Pivx.
Oh okk i found out how solve issue with autogen, it requires to add some files.
For the block not start with coinbase error i think i found out too but it might require to fork it maybe i am not sure at 100% . i will try it on pool soon,
Do you have a discord server please it will be easier to send you the files for the githug and autogen error

, you can send the link in p.m in you prefer
Thanks
