Patch upon patch on a disasterous hardfork that should never have been accepted in the first place. Guys, take your losses. Roll back to the moment of the hardfork, figure out a way to compensate those negatively affected by a rollback and try again for HF20-lite in a few months, preferably with the current #21 to #40 witnesses as new top twenty bunch.

*Ceterum censeo HF20 esse delendam*
