Hi headoff -

Can you let me know the exact steps you took that caused the crash? (For Example, Opened the Editor from the Launcher, Opened the Project, Built Lighting, Opened World Settings, Expanded Lightmass, Double Clicked on Light Map Texture Asset)

As much information as you can. Also if you can upload a copy of log files associated with the crash you will be looking for a subfolder in the following folder created at the time of your crash:

C:\Users\UserName\AppData\Local\Microsoft\Windows\WER\ReportQueue

Thank You

Hi Eric!

Thank You for answer.

I worked with the scene and then saved it and closed.
On next day I tried to open the scene but got the crash. With Editor, with Launcher, with loading in “open level” and in “content browser”. And I got every time this bug message ((

I attached the RAR with reports

Hi headoff -

After a look through your crash logs, I was able to narrow down the issue and it has already been addressed in out internal branch of the engine. A fix should be forth coming in an engine release.

Thank You
