Crash When Editing Events in Live Session

Unreal Editor for Fortnite

What Type of Bug are you experiencing?

Live Edit

Summary

If you’ve selected a device/prop with events in UEFN, and then edit the events of the same device in a live session, it will crash UEFN upon confirming the changes.

Steps to Reproduce

  1. Place 2 or more devices that can use direct event binding.
  2. Setup Direct Event Binding between the devices in a Live Session.
  3. Select one of the devices that has DEB configured in UEFN (potentially need to view list of events in the properties viewer, but the properties being opened should suffice).
  4. Delete events from the selected device in the Live Session.

Expected Result

The properties list would update with the new event bindings, or UEFN would automatically de-select the device so you can click it and see the updated events.

Observed Result

UEFN freezes (essentially crashing), eating an ever-increasing amount of RAM until it’s force quit in Task Manager.

Platform(s)

Windows 10

Additional Notes

I had forgot the device was selected in UEFN honestly, but at the same time, would hate for others to lose work from a crash due to this.
