Summary

Summary of the issue :

  • So technically assets/devices can disappear while the Unreal Editor for Fortnite and the Fortnite game is running at the same time. More precisely when we are working inside the Editor ( changing something in the level, moving things around etc. ) and inside the Fortnite game we are in our session - in edit mode ( we ended the session and with that we entered to the Edit mode ).

Steps to Reproduce

Steps to reproduce the issue :

  1. Open your Island inside the Unreal Editor for Fortnite
  2. Once your Island is loaded, launch a session from the Editor
  3. When the Session is loaded press the ‘Esc’ button and click on the ‘End game’
  4. After you finished step 3 you will be enter into the Edit mode inside the Fortnite game
  5. Round a round a little bit inside the Edit mode or change one or two asset(s) or just adjust some devices
  6. Go back inside the Unreal Editor for Fornite and continue your work on your island while your Fortnite game is open ( where you are in the Edit mode )
  7. After a short period you can observe that some of your assets disappeared

Expected Result

When you complete the steps under the “Steps to reproduce” title, there is a huge chance that you will lose some assets from your level without any reason.

Observed Result

This issue happens out of nowhere and randomly. My observation says this issue happens because of the playtesting system. More precisely when you can add/delete/change things on two different platform at the same time. In our case its UEFN and Fortnite.

Platform(s)

I observed this issue on PC and I don’t know is it happening on other platforms or not because I did not tested that.

Additional Notes

My observation on this issue tells me that the root of this issue comes from the UEFN/Fortnite playtesting feature.
