How to Fix Unity Addressables Serving Stale Content After a Catalog Change

You published a content update but players still see the old assets. Addressables cached the catalog and bundles. You have to ask it to check for catalog updates and clear the stale cached entries.

How to fix it

1. Check for catalog updates

Call Addressables.CheckForCatalogUpdates and, if any are returned, UpdateCatalogs at runtime so the system learns about the new content.

2. Clear stale bundles

Use Addressables.ClearDependencyCacheAsync for updated keys so the loader fetches the new bundles instead of replaying cached ones.

3. Host a remote catalog

Build with a remote catalog so content can be updated and re-fetched without shipping a whole new app build each time.

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.
