Quick answer: Enable the cheat manager (bShowMouseCursor/EnableCheats path or a development-only flag), or move always-available debug commands to a UFUNCTION exec on the PlayerController.

Your custom Unreal console commands work in some builds and report Command not recognized in others. The cause is that UCheatManager exec functions only exist when the cheat manager is instantiated, which does not happen by default in shipping-like configs.

How to fix it

1. Know where exec functions live

Console commands come from UFUNCTION(exec) on objects in the exec chain: the cheat manager, player controller, pawn, or game mode. A command on the cheat manager only works when that manager exists.

2. Enable the cheat manager for testing

The cheat manager is created when cheats are enabled (e.g. EnableCheats / development builds). Ensure your build path instantiates it, or your CheatManager commands will not register.

3. Move core debug commands up the chain

For commands you need regardless of cheats, put the exec UFUNCTION on the APlayerController so it is always available, not gated behind the cheat manager.

4. Strip cheats from shipping

Keep cheat commands compiled out of shipping builds so the unrecognized error in release is intentional, and confirm the CheatManager class is set on the player controller for dev builds.

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 Unreal Engine 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.
