I already created a page in Answers, but never got an answer:
I uploaded a new version of a file for a wiki page. If you download the file it’s different than the one displayed in the list of versions, and also if you go to the image in the wiki page it’s the old one.
The first image is still showing the old file. A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
So the versions don’t work.
