just done the 3GB update 22:00 GMT 29 June for Fortnite/UEFN
As usual have run Verify to fix any potential problems
How to run “verify” after an update to avoid problems
Loaded High Garden Sanatorium version 2.1 in Fortnite
cant find anything wrong
Obviously we are not collaborators as in
Collaborating in Unreal Editor for Fortnite | Unreal Editor for Fortnite Documentation | Epic Developer Community (epicgames.com)
So as you can see have Loaded into Fortnite.
if you try UEFN try to get the Revision control to check your project is still good and working ok.
Please remember before you close your work to send your changes to revision Control
Although you may not want to actually collaborate with others its best to use the same thing as this saves your project.
If something goes wrong with your PC you can just go to another PC load up UEFN/Fortnite and pull down the project onto your PC and if an update fails then your project wont be lost.
DONT put this on OneDrive use something like
User\Owner\UnrealEngine\Projects.
Windows 11 ALWAYS puts projects on OneDrive
