How to Fix a Map Toggle That Opens and Immediately Closes

Pressing M to open the map flashes it open and shut in the same press because the toggle fires twice. Duplicate handling is the cause. Here is how to fix it.

How to fix it

1. Find the duplicate handler

Search for everywhere the map key is read; a press handled in both an input action and a per-frame poll will toggle twice. Keep only one.

2. Use an edge-triggered action

Bind to the input action's pressed event (which fires once per physical press) rather than checking IsInputKeyDown every Tick.

3. Debounce the toggle

Ignore further toggle input for a few frames after a toggle so a bounce or repeat cannot immediately flip the panel back.

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.
