I can't access these files but I asked @mita996 if he can upload the World Cup stadiums and he said that he'll do it.
I also uploaded some other files:
overlay
pedastal
subboard
trophy
wipe3d
Maybe someone can use these files or they work ingame? If you need anything else please tell me. I'll try to upload it asap.
@The Wizard Are these from FIFA19 or 2018WC DLC?
