Unreal Editor for Fortnite

What Type of Bug are you experiencing?

Live Edit

Summary

Everytime I try to press live edit, I get a popup window that says “Uploading project” and it uploads a staggering 92mb of content. My project size sits at 30% and in game and the largest memory cluster in game is around 30k.

Some extra info to spot the culprit: My map is a large island made of landscape, I have 2 road splines and I have HLODs built.

However, this upload happens everytime I launch live edit.

Steps to Reproduce

Open “mercenaries” project (ask Halcyon)
Open live edit initially
Go to landscape and sculpt a little
Press sync again with live edit

Expected Result

Landscape reuploads when syncing

Observed Result

92mb worth of content uploads.
