Summary
Hi Epic Team,
After the latest Fortnite update, my UEFN island’s memory suddenly increased by about 15,000, even though I didn’t add or change anything.
When I delete items to try reducing the memory, the total doesn’t go down — sometimes it even increases instead. Before the update, everything was normal and within the memory limit.
It looks like the update may have affected how memory is calculated or displayed in UEFN.
Could you please check if this is a known issue or let us know if a fix is planned?
Thanks for your help!

Memory
Steps to Reproduce
Open the UEFN project (existing island).
Load the island after the latest update.
Check memory usage — notice that it has increased by around 15,000.
Delete some props or assets and check memory again.
Observe that the memory doesn’t decrease (sometimes it even increases).
Expected Result
Deleting assets should reduce the total memory usage as normal, and memory should remain stable if no new items are added.
Observed Result
Memory usage increased after the update without adding anything, and deleting items doesn’t reduce memory — in some cases, it increases instead.
