Delirious debuffs not displaying

I recently attempted a map influenced by several delirium orbs. I kept dying, and figured out that my flasks were not refilling even though I was hitting and killing monsters. Some googling tells me that there is a debuff from delirium that can prevent you from getting charges, but I saw nothing on my screen to indicate that I might be getting that effect. I was hitting bloodline monsters with the tags of "shared boon" "resist elemental damage" and "Lightning Damage" but nothing else. Map did not have flask-related modifiers. Only reason for consistently being unable to gain flask charges must be some undisplayed effect.
