Spells: Cure Disease & Cure Poison apparently not working?

[Slust]

I've lately been feeling that Cure Disease and Cure Poison are not actually working. I've been fighting Ogres in West Karana that typically cast

Affliction
1: Increase Disease Counter by 4
2: Decrease Hitpoints by 20 (L19) to 25 (L24) per tick
3: Decrease HP when cast by 30

Envenomed Breath
1: Increase Poison Counter by 3
2: Decrease HP when cast by 30
3: Decrease Hitpoints by 59 (L24) to 71 (L36) per tick

and whenever I try to drop either appropriate Cure spell

Cure Disease
1: Decrease Disease Counter by 1 (L1) to 4 (L12)

Cure Poison
1: Decrease Poison Counter by 1 (L1) to 4 (L12)

nothing happens. I've cast the Cures 5 times each and none remove the effects, which really sucks because I have to instead counter the DoTs with heals, which is way less mana efficient and could potentially kill me if I end the fight with too low mana and health to survive.

Additionally I was killing crag spiders in East Karana and there was a warrior who got the debuff from fighting evil eyes

Infectious Spores
1: Increase Disease Counter by 3
2: Decrease HP when cast by 10
3: Decrease Hitpoints by 4 per tick

and had someone spamming him with Cure Disease and it wasn't removing. I don't know what his fate became, as that is the only spell in the game with no duration, but he was also complaining of the Cure spell not working.

Has anyone else experienced something like this lately?
