Summary
I’m experiencing a critical issue where my UEFN project’s download size randomly increases between sessions, despite no significant changes to project assets.
The issue also affects Creator Portal, preventing me from publishing my island because the download size exceeds the 400 MiB limit.
Project Size Comparison:
Version 487: Upload 768.11 MiB | Download 332.05 MiB
Version 490: Upload 768.13 MiB | Download 746.01 MiB
Unexpected download-size increase: 413.96 MiB
Texture and Static Mesh sizes remain practically identical.

Steps to Reproduce
- Open the UEFN project.
2.Launch a session and calculate project size.
3.Observe a download size of approximately 332 MiB in some sessions.
4.In other sessions or private versions, the calculated download size increases to approximately 746 MiB.
5.Check Creator Portal, which also displays the inflated size.
Expected Result
Download size should remain consistent when project assets are unchanged.
Observed Result
Download size fluctuates by more than 400 MiB without corresponding asset changes, making the project impossible to publish when the inflated size is reported.

Additional Notes
Publishing blocked. This is affecting active development and preventing release.
I have attached screenshots showing the project-size differences.
Please investigate whether this is related to inconsistent cooking, packaging, or download-size calculation.
