@yehey - While this could have avoided with a validation error, since the blockchain managed to work without hitting this error itself is a proof that its not major one. This is like a rocket launch failing and I think we all should realize that the software systems are prone to fail no matter how much quality assurance is done. While its bad that this happened, I think we should look the ability of the team to come up with a working patch with only minor chain base version mismatch in such a short time.

To Err is common but to fix them so quickly desrves some good words in IMHO
