I was feeling the EXACT way last week. Then I realized what TH just told you. Did we make mistakes, yes. Did we fail to see what was happening right in front of our eyes, yes. Is it all out fault, NO. There were two people in your M, both were resposible for making it work and to communicate when it wasn't.
The bricks did not leave all at once for me, but I am a few tons lighter today than I was last week.
