How to Fix a Fast-Travel Point Not Unlocking on First Visit in Unity

Standing on a new fast-travel marker should unlock it for good. If it relocks on reload, the unlock never reached the save. Here is how to persist it.

How to fix it

1. Write to persistent state

On entering a waypoint trigger, add its id to a saved set like unlockedWaypoints in your persistent game data, not just a scene-local list.

2. Initialize before triggers

Ensure the unlocked set is loaded before triggers run on scene start, so an early visit is not lost to an uninitialized container.

3. Guard re-entry

Use a set so re-entering an already-unlocked point is idempotent and does not duplicate or reset the entry.

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.
