Please make also sure #MKStack works well as well.
Discussion
#mkstack works fine, but will have better support for Zaps and NWC support soon.
MKStack sometimes crashes as well, that's why I had to restart projects in Sharespeare and that's also when it starts to spit out the "no such file and directory".
... error.
The architecture of NSPs or using them with Shakespeare is going to completely change. That error won't happen in the future.
