Quick answer: Drive followers from a recorded trail of the leader's past positions, placing each follower at a fixed distance back along that trail so spacing holds even when stopped.

When the party stops walking, the conga line should keep its spacing, not telescope into one sprite. If yours bunches up, followers chase position with no floor. Here is the trail fix.

How to fix it

1. Record a breadcrumb trail

Each frame, append the leader's position to a history buffer when it has moved past a small threshold.

2. Place followers along the trail

Position follower N at a fixed cumulative distance back along the recorded trail, so each keeps a consistent gap regardless of speed.

3. Freeze on stop

When the leader is not moving, stop advancing followers along the trail so they hold their last spaced positions instead of creeping closer.

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.

A crash you can name from its stack trace is a crash you can usually fix in minutes.
