Known Launch Issue

The August 21 patch says some achievements were broken at launch, including full-set unlock behavior.

Checklist

Recheck the relevant set or collectible threshold, then relaunch Steam before assuming the achievement is permanently broken.

Collection Achievements

For Blue, White, Red and Purple set achievements, confirm the underlying base-card set first. Foil achievements are separate and should not be mixed into base-set requirements.

Upgrade Achievements

For Champion and Power Overwhelming, verify whether the stat or all upgrades stayed purchased after reload. If upgrades reset, solve that first.

When to Wait

If you completed the requirement during a patch window, restart Steam and the game, then check again before changing save files.
