I noticed i have problem with chapte 11 Aric Jordan wasn't there i first tought it is a bug about chapter 11 but When trying many options to overcome bug i noticed my companion list doesn't have alliance specialists, then i noticed i, can't enter warroom at odessen, so this is a bug about chapter 9 progression.
I tried to do chapter 9 two times. When i start chapter 9 my alliance specialist come back to my companion list, but when i finish it, they disappear again and i can't enter war room again.
I think you can over come this main problem when doing chapter 10 but it will hit you at chapter 11 so many people will think chapter 11 is bugged.
