Yeah beef between nukkye and keloqz is most likely. If you follow nukkye long enough, it becomes apparent quite quickly that he is the kind of person for whom things have to be done in a certain and specific way, i.e. one could argue that he has little flexibility and is more on the uncompromising side. If there is a significant enough deviation from his vision, then nukkye has a tendency to cause friction which ends up in situations like this.
Not trying to shit on nukkye here, but one would be delusional to deny this, especially if one had followed him since his cs:go days. It's just a personality trait that he seems to have not yet completely managed to overcome yet, for better or worse.
