Maybe from the new team-only area heals thing?
I have noticed over the last few days heals from mob patchers not landing on other mob members.
The "Mobious Code" icon you see is the same as Repair RSI 4.0. I have been noticing this with the level 16 to 26 NPCs using individual heals because I have been playing my alts more. I haven't paid attention if mission NPCs are healing challenged as well.

NPCs aren't supposed to have AOE heals/buffs. Although...it occurs to me now that I did give them to the Tigers back when I made those Pandora's Box NPCs. I wonder how I managed to forget about that when we switched all the AOE heals/buffs to team-only... Well, I'll just have to give them single-target heal/buffs instead. Are you seeing this with any other NPCs?
There are lots of NPCs with single-target heals, and those are still supposed to work. By "not working" do you mean that the NPC being given the heal isn't actually getting any health back?
