What causes Steam language overriding the in-game selection?

Your build reads the Steam interface language on every launch and applies it, clobbering the language the player explicitly selected in your settings menu.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix Steam Language Overriding the Player's In-Game Choice

Quick answer: Read the Steam launch language only as the initial default, then prefer a stored in-game override on subsequent launches so the player's choice sticks.

Reading the Steam language every boot means a player who picks Japanese in your menu keeps getting reverted. Honoring an explicit override fixes it. Here is how.

How to fix it

1. Use Steam language as a default only

Call the Steamworks current/launch game language to seed the locale on first run, but do not re-apply it unconditionally on every startup.

2. Prefer a stored in-game override

If the player has explicitly chosen a language in your settings, persist that and load it ahead of the Steam value, so their choice survives restarts.

3. Map Steam API language names to your codes

Steam returns API language names like schinese; map these to your internal locale codes so detection resolves to the correct shipped language.

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.

Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
