(Critical) UEFN Lag spike while in editor, then all decals lost their materials

Summary

This is a very destructive bug and I ve lost so much work to it. I had live edit open and was placing decals in UEFN, then suddenly UEFN had a lag spike (not responsive for 0.5 secs) and all decals disappeared from the scene, showing a the default spongy material that indicates no decal was selected. Now all my work has gone to waste, as autosave also fired up and saved this state with no materials in the decals. I have to replace everything again, and that took a good hour to do.

This can also happen with Audio player devices and their slotted audio files on the scene. Same issue.

Thank you, I’ve passed that along.
