Groups where members weren't close/didn't get along?

I'm really surprised there aren't more groups affected by poor chemistry, there must be groups where the members just...don't get along right? I know that Suzy and the rest of Miss A weren't close, and Seungri with the rest of BIGBANG.

I guess you hear more about bad blood in nugu groups because big companies have the trainees and resources to craft groups that work well together.
