in my experience, the plays where the screwup is on the retail side, they don't halt it....because no MM is getting hurt... like GLKC and PAIV..
Screwups where it was on the MM/broker/company side.. GVRP, BCIT, PAVC - the trading gets either actually suspended for a time, or the brokers just won't trade it...
AWYB seems to fall into the former group, so should be good to go.
