Fortnite Update v13.40 will focus heavily on bugs and glitches in the current game. While fans are patiently waiting for Fortnite's new cars, the new vehicles were just delayed yet again. That will cause a small content draught, but that doesn't mean Epic Games is doing nothing. The developer is still improving the game in any way they can.
The Fortnite community can view upcoming changes on the public Trello board where Epic Games updates and posts upcoming changes and fixes.
Fortnite Update v13.40 Will Have Multiple Bug Fixes
There are things listed like Inability to edit floors and roofs at certain angles, 'Lock Input Method as Mouse' does not lock the input method, and Mouse cursor appearing on PC when playing with controller.
These things seem like minor issues, but to anyone that's been affected by one of them, it's a great feeling knowing Epic Games is aware and working on a fix. These patches bring peace of mind to the community and reassurance that Epic Games is always working on a fix.
