Quick answer: Re-resolve the active user when the title gains focus or a switch event fires, scope all save and stat I/O to that resolved user handle, and reload state for the new profile.

If a console game shows the wrong save after someone switches accounts, you cached a stale user handle. The OS can change the active user at any time, and saves are per-user.

How to fix it

1. Re-resolve on focus

Query the current active user when the title resumes or a user-change event arrives, rather than reusing the handle captured at launch.

2. Scope I/O to the user

Pass the active user handle into every save, load, and stats call so data is read from and written to the correct profile's storage.

3. Reload on switch

When the active user changes, save the previous user's state, then reload the new user's save and profile so the session reflects who is now playing.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

A crash you can name from its stack trace is a crash you can usually fix in minutes.
