When the leader leaves please WARN
This happened to me. I was the leader and I left forgetting to appoint a leader, and it fell to a co. Luckily he was a close friend.
One would say "why forget?" Well, we all are human and forgetting is nature.
And others may say "why appoint co someone you can't trust?" That is not always a valid logic because sometimes we have to give co to a really good attacker as a reward, but still not 100% trustworthy not to kick us all.
When we change the acc, SC forces us to type CONFIRM every time, with no good reason, and at many other places SC asks us to confirm. So why is the MOST IMPORTANT thing just thrown to somebody without a warning?
Please warn "You are about to leave. Please appoint a new leader"
This is not a big thing for SC, please do it.
