I don't think the hacking malicious. People just make mistakes. Random example: if candidate is below the viability threshold, that group is supposed to disband and join another group. You could have a mistake where, on the 2nd round, two non-viable groups merge and form a viable group. For example, maybe Biden is at 14% and Klobuchar is at 2%. Under rules, those groups are both non-viable. But you could easily see a mistake where the caucus operators allow the 2% Klobuchar group to "merge" with the Biden group.
