Looks like healbot is currently bugged for rshams. You're able to see curses, but no magic debufs will show up automatically; they have to be added manually. Just a quick heads-up. Depending on how fast they get a fix out, you may want to prep for switching to another raid frame for raiding on Tuesday if you're a healbot user. Adding every magic debuff as a custom debuff is an option, but it's a pain in the butt.
Like I said, just a quick heads-up. Carry on, ladies and gents.
