(see previous post for a more detailed description of the bug and actions taken)
Developers have confirmed that the bug exists but will be fixed with the upcoming (next week) hard fork HF25.
At this time, I have reenabled stabilizer using HIVE to buy HBD when the price is less than 1 USD. Although HBD isn't presently convertable into 1 USD worth of HIVE, the proper functioning of the conversion mechanism should be restored next week, so it is reasonable to consider HBD as still being "worth" 1 USD now.
Converting of HBD into HIVE remains suspended and will be restored after the hard fork (assuming market conditions remain safely above the haircut range).
