According to @timcliff who is a top witness (and totally on top of what's going on)...

"We've successfully forked the blockchain, the new RC system took all of the pre-hardfork transactions into account, which made transactions really expensive (in terms of RCs) and also took most users RC balance into the negative. There is a patch (20.3 which is currently tagged as master) which witnesses are applying to address the issue. Even after the patch, it is expected that it will take some time (around a week or so) for the new RC system to reach an equilibrium and be charging the right amount of RCs to users based on the desired usage limits we want to enforce on the blockchain."

여기서 중요한 내용은 equilibrium 즉, 시스템 안정화가 되면 (약 1주일후) RC가 초기에 세팅해놓은 값으로 떨어질것이다. 즉, 그말은 반대로 해석하면 지금 RC가 떨어지는 것은 정상적인 수치가 아니라는 뜻이겠죠? 버그는 아니더라도 적어도 현 상태가 최종 상태가 아니라는 희망이 있네요. ^^
