Quick answer: Apply refueling and tire changes as discrete state writes when the pit service timer completes while the car is stationary in the box, and validate the car is in the pit zone.

Drivers serve a full pit stop but come out with the same worn tires and low fuel. Applying the service as explicit state changes on stop completion makes the pit actually do something.

How to fix it

1. Gate service on a valid, stopped stop

Only run the service when the car is stationary inside the pit box for the required duration. Cancel and retry if it leaves early, so a drive-through does not grant a full stop.

2. Apply fuel and tire writes on completion

When the timer finishes, set fuel to the requested amount and reset tire wear for the chosen compound in one explicit step, after which control returns to the driver.

3. Add the pit time as a real cost

Make the stationary time and pit-lane speed limit a genuine time loss so the strategy trade-off between stopping and staying out is meaningful.

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.

The bug you can't reproduce isn't gone — it's just invisible until you capture it from the player's device.
