The interesting part is that your progress is saved on Microsoft’s servers, and wiping it manually is practically impossible unless you play completely offline or buy the game on a new account.
The online profile doesn’t just list which campaigns you finished—it also stores the date and the highest difficulty cleared. Anyone can look this up, for example:
- Mine – Stats - Age of Empires - World's Edge Studio
- noxius – Stats - Age of Empires - World's Edge Studio
- A friend who still has full completion – Stats - Age of Empires - World's Edge Studio
When you query the Relic backend API directly you get the raw JSON that the game itself consumes, complete with extra metadata such as the stat-group IDs that tie each campaign to your completion record.
So what’s missing from all profiles—not even displaying as “0/n” like other unfinished campaigns? Every Caucasus / Mountain Royals campaign (Thoros, Tamar, Ismail) and all Victors & Vanquished scenarios.
That strongly suggests the data itself wasn’t erased; instead, those campaigns were never added to the stat groups the game pulls from the server. When your local player.nfp file is lost or corrupted, the game regenerates it at launch using the server copy—so any campaign that isn’t part of that server payload reappears as “not started.”
In short, this looks like an oversight in how the newer campaigns were wired into the online stat-tracking system, not a failure to save our progress in the first place.
