Suggested next step

Record build, civilization, campaign Act or Tycoon mode, DLC and multiplayer context; update-specific Home City rules are not universal across every mode.

Separate the three changes

World's Edge calls out persistent campaign level, reset selected campaign cards/custom decks, and removal of hidden card-level requirements. Those are different outcomes; a reset deck can coexist with a retained level.

Audit the campaign state before grinding

The patch notes describe an intentional progression-system change. A repeat of an early mission is not needed merely to restore the old per-mission level behavior; first inspect the active campaign Home City, Act and selected cards.

  1. Check the installed build/update history and confirm Update 19.18309 or later is present.
  2. Record whether you are in a campaign, the Act, campaign civilization and active Home City.
  3. Compare current Home City level with the highest level you had achieved; the notes say that highest level carries over.
  4. Open the campaign Home City and reselect cards/custom deck if they were among the selections reset by the update.
  5. Check the card's current UI requirement instead of relying on an old hidden-level guide.
  6. If progress appears missing beyond these stated changes, use official support with platform, storefront, campaign and civilization; do not post account identifiers or assume a reset is normal.

Ask the community with the update context

For player comparison, include the build, storefront, campaign Act and civilization, and distinguish a reset deck from a lost level. Older posts may describe the pre-update per-mission system; treat them as dated reports rather than current rules.

Frequently asked questions

Did Update 19.18309 reset my highest Home City level?

The official notes say the highest achieved level safely carries over; selected campaign cards and custom decks are reset.

Does campaign progression now persist across every civilization?

The notes say across each Act and across specific civilizations for the Asian Dynasties campaigns; check the campaign/civilization scope rather than assuming one universal pool.

Can I use this to troubleshoot multiplayer deck unlocks?

No. This guide is limited to campaign Home City progression described in the update.
