While there is a rule in LibPlayerSpells (under druid's COOLDOWN AURA PERSONAL SURVIVAL) and ABA's config confirms it being set up, there is no highlighting whatsoever. The spell has 3 charges and does not show a highlight border or a flashing animation.

I have such errors since I switched to exact buff identifier matches (which was needed for some spell). Sometimes the buff id is different from the spell ones. You'll have to find the exact buff id. I have a helper addon somewhere maybe I'll publish it somehow.

I've just checked: Seems to be 132402.
