Assembled artifacts in Heroes of Might and Magic V.

message from Mos.keen: I've been fighting against her for a long time... my brain is turning into undead!!,

fix it, otherwise they'll give you a warning or even ban you...

so, the "Cry of Horror" skill stopped working even after I removed these 2 items... Is this a bug?

I didn't have the exact same issue, but something similar happened:
So, I equipped 6 dragon artifacts on my hero, then removed one, but the stats (+4 to parameters) remained, it's a miracle ;):)
