I had found that the units were indeed available to Balthasar Gelt's faction, The Golden Order. In the campaign. Not custom battles, and neither were they available there for The Huntsmarshal either. So I added a record for each unit to be available to both.

Found some rogue contact effects that friggin' somehow got added to projectiles and explosions they shouldn't be on.

I forgot to elaborate on the fix that was issued for this specific update.

So, a long time ago I wanted to make these units available to the Colonies and Southern Realms factions like Tilea, Estalia, and Border Princes. Well, the Southern Realms factions all had a duplicate version of the blacksmith building chain with a different tag in the database. I had to make copies of all my units that used the blacksmith as an additional building requirement, which I did. This update did away with that redundancy, so I was left with several unit records which referenced a building chain that no longer existed. That was the problem causing the crash at start up. Now that the building redundancy has been cleared up by CA, I went ahead and removed the unnecessary unit records made to accommodate for that issue. Maybe the units are still available to the Southern Realms, admittedly I have not yet tested that, however I do know they are in the recruitment list for Wulfhart's campaign in the Eye of the Vortex.
