Well, I found out that someone marked:
* node 4 for deletion at 08:35 29/04/2016 * node 3 for deletion at 08:36 29/04/2016
However, no one press "Deploy Changes" after that. The last hit of Deploy Changes was at 07:26 29/04/2016 and ended with error at 08:26 29/04/2016.
That basically means, there were no chance to do "node removal" since no one hit "Deploy Changes".
According to that investigation, I move that bug to Invalid.
