Can't continue orc campaign

I currently have 3 missions and none of them are able to be completed

Mok Massa - Defending the Tyrant - both armies you get sent to kill refuse to update the quest unless I'm missing something I've cleared the map of units in every difficulty setting and have yet to receive credit

Krak Urnen - The Wizard Hunt - Game crashes to desktop every time I attempt to load the mission

Rafas - Contact with elves - Rafas flat out doesn't exist anywhere in Nokkrasol

okay I randomly got "The Wizard Hunt" mission to load by just bringing my hero and 4 berserker units, the other dozen or so unit combos I tried didn't seem to work, maybe I just got lucky.
