I was just dealing with this kind of error last week #4231 so I hope it is fixed in a master version. Have you tried with a current master version?

While checking this bug, I found a new one. 😅

Select var C and subgroup D. I can reopen a new issue if this one is not a duplicate.

@ajdapretnar I tried to reproduce this error but I can. What happens in your case? Does it returns an error or just show the wrong statistics?

[ajdapretnar]

@PrimozGodec You are right, I guess I forgot to run pip install -e . to build the latest C files. Closing this.

[PrimozGodec]

Yep, that could be a reason?
