I don’t really know what it causes but it happens everytime. I move the 5 objects into the Subfolder, make them invisible, go to the terrain tool … stuck.

Hi ,

Does this happen on a clean project with no additional content? Further, can you post your logs (located in \UnrealProject\PROJECTNAME\saved\logs) so we can see what might be occurring? Thank you!

I can’t post all the files in one archive … tell me if I shall post all of them individually.

I will test it in a blank project as soon as possible.

For now I uploaded them to Firedrive.com. You can choose the format:
