Yea; same issue; made a fork on github under jminer with changes to get nicehash and base working again; until nemo does a update at least. His code is far superior to my crude hacking. Also the nanashi would re-download every single time it used; mistmatch somewhere. Noticed the failed ones are dropping a -d on end of command line; some type of feature that is not yet implemented.

Dropped in latest ccminer; although it looks like alexis still beats its on my 1080TI rig for most hashes.
Also added in a USD column; as my simple brain doesn't work well in BTC. Will poke at making it dynamic and grabbing values from here:

Would be simple enough to allow any currency via var; once i figure out windows pshell scripting a bit more; traditionally a linux DEV.
Nemo; let me know if you want another collaborator on your base project, work as a DEV in RL, typically work with PR model (felt naughty committing to master on fork).
Check out this fork of the original, has many nice features
