Hi,
If you have a problem with 99% in game and can not have this 100% read it!!!
Last time i had 99% in game and can not have this 100% i was looking for help on many websites and cant find any help. In "Nurner" my mission was called Zadnayi Zind i have all orks dominated, so i gave random orks to kill me after it they jumped in army. Third time when i died they guy who killed me gave me a nemesis mision in Nurner and after it i had my 100% in game.

I think this gonna work in all maps and i dont know how many times you have to died but I'm sure its gonna work after some deaths.

I hope i helped you to get 100% in game :)
