I think the "god dammit slowking no topic convo" is a perfect example of this. We had to move to a new coco because @ThatOneSlowking added SO MANY PEOPLE to our convo when the limit was raised.This has happened before, leading to the remaining people having to make a new conversation. It was a pain, since all the relevant information was spread out over about 6 pages of responses in the old conversation.
I'm sure it'll happen again too.
