How to Fix a Save Point Writing to the Wrong Slot After Cancelling in Unity

If saving at a crystal overwrites a slot the player did not pick, a stale selection index leaked between menu opens. Here is how to keep selection fresh.

How to fix it

1. Reset selection on open

When the save menu opens, default the highlighted slot deterministically (e.g. last used or slot 0) rather than reusing whatever was selected before.

2. Confirm against the highlight

Have the confirm handler read the slot currently under the cursor at confirm time, not a cached index set earlier.

3. Require explicit confirmation

Show an overwrite-confirm prompt naming the slot so an accidental press cannot silently clobber a different save.

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 Unity 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.
