Issues and Bug Reporting

Summary

Since v40.0 rolled out, our edit session gameplay has become unplayable, while private published maps with the same everything work perfectly. Obviously, this means that in order for us to test anything, we need to publish a private map every time, which is extremely time consuming and frustrating.

What Type of Bug are you experiencing?

Devices

Steps to Reproduce

1. Load a project from pre-40.0.

2. Press to launch edit session.

3. Play edit session.

4. Edit session gameplay is broken and vastly inconsistent with published version of same exact map.

Expected Result

I expect the edit session gameplay to be at least somewhat consistent with the published version of the map as its always been up until v40.0.

Observed Result

A variety of devices, including skydive volumes and cinematic devices, no longer function in the editor gameplay. These devices work perfectly when the map is published.

Platform(s)

All platforms impacted since this is a UEFN edit session issue.
