Enemies ignoring counterspell

In a Random encounter with a High Priest and a Warlord the High Priest successfully countered my wizards spell. On its go it casts Flamestrike which my Wizard countered with a roll of 28 (success) though it still casts the spell. There are more and more instances of the enemies ignoring the rules though the game says its successful. Things like Faerie Fire on targets but they are still classed as invisible and sneak attack, See invisible not revealing invisible creatures, fireballs being totally ignored (no damage dealt) though they failed saves.
