What causes fast travel bugs?

Fast travel teleports the player before the destination is loaded, places them at a bad spot, or does not reset velocity and state, so they fall through the world, land wrong, or keep stale state.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix Fast Travel Bugs in an Open-World Game

Quick answer: Load the destination before placing the player, spawn at a validated point, and reset velocity and transient state on arrival.

Fast travel bugs are loading and placement order issues. Here is how to fix them.

How to fix it

1. Load before placing

Ensure the destination area is loaded (or stream it) before placing the player there. Teleporting into unloaded geometry drops the player through the world or onto missing collision.

2. Spawn at a validated point

Place the player at a defined, clear arrival point at the destination, checked against geometry, rather than raw coordinates that might be inside something. Validate the spot so they land safely.

3. Reset velocity and state

Zero out velocity and clear transient state (falling, combat) on arrival so the player does not carry momentum or a mid-action state into the new location, which causes odd behavior right after travel.

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 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.

Ship the fix, watch the signature disappear from the next build. That's how you know it's really gone.
