Hello Fortnite developers,

v40.40 has no new known issues from pre-release testing. It does include a partial fix for a custom items issue introduced in v40.30. We’ll update this thread as a fix rolls out or timelines change.

- In v40.40, icon overrides are fixed—rarity and description overrides still revert to defaults in-game
- Fully custom items are not impacted
