Hi,
From my understanding, all of the timelines appear to allow enough timeline accumulation to complete the timeline twice, except for “The Age of Winter”. It requires 900 stability to fight Heorot, which is consumed, but only caps out at 1700 stability. This is counter to the 900/1800 observed in “Spirits of Fire”, the 850/1700 observed in “Reign of Dragons”, and the 750/1500 observed in “Fall of the Outcasts”.
Is this an oversight, or intended behaviour? It means that while I can chain two boss fights in the other timelines, I can only do one on this timeline before needing to traverse the timeline again.
EDIT: It looks like it was fixed recently, I updated my client and I was able to get to 1800 stability.
