Bug with Champions of Just quest.

Quest: Champions of the Just.
Part of walkthrough: Going out of the Main Hall while templar NPCs defend it.
Game 1 – female elf mage, did the banners ritual in the beginning.
Game 2 – male elf mage, did the banners ritual in the beginning.
Game 3 – female qunari warrior, did the banners ritual in the beginning.
Game 4 – female human mage, didn’t do the quest (sided with mages).
Game 5 – male qunari mage, skipped the banners ritual in the beginning.
Game 6 (current) – male elf mage skipped the banners ritual in the beginning.

What I used to get: The state of Main Hall and amount of wounded/dead friendly NPC templars changed according to the time I spent outside on getting quest abjectives. 
Problem with the last 2 runs through that didn’t appear before:
When I go outside of Main Hall, no matter how little time I was outside (checked with both exits from hall) and no matter how little my "Main Hall state" bar looses - all NPC templars but ser Barris (and veterans later) are dead once I come back to Main Hall the first time.
Result: In the end of quest I see plenty of Templars along with ser Barris, so I could conclude that game reads state of Hall but it is not shown to me and doesn't allow to know my current state during the quest.
Side note: I don’t know if it’s the issue with last 2 patches or it could have something to do with skipping/doing banners ritual (as it’s the only difference in my games).
