Version 8.2.5.7 brings changes to separate memory structures, as part of this saved settings will move into the addon HealBot_Data.
If you have already updated...
Unfortunately, with Beta 2, I'm still unable to see the Tainted debuff on my Focus frame.
I've also noticed another new, strange behavior: When my druid switches from Resto to Balance, I continue to see magic debuffs (which he can't dispel) in battlegrounds, even though the "Spell to remove debuffs" is correctly set as Remove Corruption.
