In my case, their employee is just making fun of me.
Repeated demand to delete texture files that are left for customization. And also demands to rename files that are created by Epic themselves and are in the demo folder.
There are not enough problems with sales in FAB, and somewhere they have hired completely incompetent employees who have never even seen their own rules for publication.
And apparently unable to distinguish content created by Epic from other content. And this started quite recently, this is not the first time when they want changes in their own files that the Epic company called so. Although there were no changes in the publication rules.
