hi @Cleverlike_Studios ,
This appeared on UEFN same as yours yesterday. This morning 13 June 06:00 UTC 01:00 EST a large patch (1.5GB) . Friday patch seems to have fixed all the disallowed items in your output log.
Created a new Landscape Feature Example project at 06:00 EST on HARD drive NOT OneDrive.
Built the Landscape items needs updating and in Launch options selected “Validate” project.
Looks like the patch has fixed this in my UK version anyway
