Before diving into the patch content, it is crucial to understand why two different numbers appear for what seems like the same update.
Despite the numerical difference, both versions represent the same codebase and the same patch contents. The "1.608.0.3" build was released approximately 48 hours after 1.607.4.9.3 to address a critical hotfix that only affected Steam Deck and Steam Input configurations.
For three weeks prior to this update, a glitch allowed players to infinitely redeem Super Wheelspins by manipulating the game’s autosave timing. Users would force-quit the game immediately after spinning but before the reward animation completed, causing the game to award credits and cars while retaining the Wheelspin token.
How the 1607493 e patched version fixes this:
Playground Games implemented a server-side reward acknowledgment. The client (your PC or Xbox) can no longer finalize a reward without a two-way handshake with the FH5 backend. If the handshake fails, the Wheelspin token is immediately revoked. The "e" in the patch notes stands for "entitlement verification." Attempting the old force-quit method now results in a temporary suspension from the Horizon Auction House.
