I do not see the folder that you are talking about. When you say that the images are missing can you confirm that this folder was in the project by default? The only thing in my slate folder is a folder name “Fonts”. Could you clarify when exactly it was that you found the image folder?
We were able to find the lines of code that you are referring to and have written up a report ( UE-18306). I have submitted the report to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. These bits of code appear to be referencing a folder that does not exist and so I cannot acquire the assets referenced there in. Thank you for your time and information.
