While the spelling is suspicious and enough to make me question if its responsible for why we have had such shit luck, I am like 99% sure that the game doesn't call spell/event/npc names, but rather their IDs. So if a typo was responsible it would likely be along the lines of the triggering event calling "Event(1234r)" instead of "Event(12345)"
Notice that for the "Send Disgraved Runecaerver Event", there is an Effect of "Send Script Event(47590)". My first guess would be that this would then call an event/spell with an id of 47590, which happens to be "Freezing Cloud Periodic (Left)", which in turn applies an aura called "Freezing Cloud".
Also of interest is the fact that "Conversation - Disgraced Runecarver" has TWO effects. "Unknown Effect(Effect #219)(746)" and "Send Script Event(47590)". The second effect is the same as above, the Freezing Cloud thing, but the first effect is interesting. Not only is the entire "Unknown Effect" thing odd as all hell, but there IS no event/spell with an ID of 219 and 746 is "First Aid".
Now this could either be evidence of a bug where the Conversation event has a typo in its script and its calling something that doesn't exist as a result, or it could simply be a sign of shoddy coding intended to break a link between something that was removed form the game and a part that was left in the game for other purposes.
My suggestion, if we are to assume that either or both of these events is tied to our HAA, is to find an NPC, spell or other event that has an effect of calling either one of those spells.
