Festival Main Stage: D-pad cannot navigate the Song Menu

Platforms: PC, PlayStation, Xbox, Nintendo Switch, MobileVersions: 42.40Updated Evidence checked

The current known-issues list still identifies a controller navigation problem in the Main Stage Song Menu, including Restart and Return to Backstage. Epic says the analog stick remains functional; the entry is not a report that every menu or controller input has failed. [1]

Documented steps

  1. Use the analog stick to navigate that Song Menu while the D-pad issue remains listed. [1]

v42.40: IS-UP-IZ04 while installing an update

Platforms: PCVersions: 42.40Updated Evidence checked

Epic says it has deployed a correction for the IS-UP-IZ04 installation error affecting some players during the latest Fortnite update. Its October 15 issue list also gives a launcher restart for anyone still seeing that exact code. This entry concerns installation, rather than a matchmaking error after the game opens. [1]

Documented steps

  1. Right-click the Epic Games Launcher icon in the Windows taskbar, choose Exit, then open the launcher again. These are Epic’s named steps for a remaining IS-UP-IZ04 message. [1]
Officially acknowledged

Mortuus X Titanium Legacy Style has the wrong colour

Platforms: PC, PlayStation, Xbox, Nintendo Switch, MobileVersions: 42.40Updated Evidence checked

Epic acknowledges that the Titanium Legacy Style can show pale purple where white is intended. The v42.40 list names 43.00 as the planned correction. That is a future target in this source, so this entry remains open rather than being described as a released fix. [1]

Official fix available

v42.40: launch crashes on certain AMD video cards

Platforms: PCVersions: 42.40Updated Evidence checked

The v42.40 notes identify a released correction for launch crashes on certain AMD video cards. Epic does not name every affected GPU in this entry. Match the failure stage and hardware to this report before assuming it explains a different crash. [1]

Official fix available

v42.40: tapping the mobile Reboot Van icon

Platforms: MobileVersions: 42.40Updated Evidence checked

Epic now lists the touch-screen Reboot Van activation problem as fixed in v42.40. This entry specifically concerns tapping the van’s on-screen icon on mobile. Keep that scope in mind when comparing a failed activation with a separate reboot or matchmaking problem. [1]

Official fix available

v42.40: vehicle keyboard bindings revert to defaults

Platforms: PCVersions: 42.40Updated Evidence checked

Epic reports a v42.40 correction for custom keyboard bindings on certain vehicles failing to apply and reverting to defaults. The entry concerns keyboard controls for those vehicles; it does not report that every controller configuration or movement-binding problem has been repaired. [1]

Official fix available

v42.30: Dynamic 3D Resolution disables itself

Platforms: PCVersions: 42.30Evidence checked

Epic’s v42.30 list records a correction for Dynamic 3D Resolution switching itself off. It also identifies a rare Text Chat failure that previously persisted until a game restart. These are two documented fixes in that earlier update, rather than evidence that every rendering or chat problem is solved. [2]
