Comparison problem at x:11/91
Dear developers,

I'm having an issue with the group comparison getting stuck at x: 11/91 forever.

The thing is that the first and second halfs of my dataset taken separately work fine, but adding subjects from one half to another results in this (screenshot attached). I can't find any systematic shifts in my data judging by the headers. Also, basic ISC for the whole dataset works fine (although there are some seemingly random NaN values in a few iterations), just not the comparison .

This error has been replicated on different systems. 

Is there something particular going on in this moment?
