Have you noticed whether this infinite Downloading issue happens to you close to when you have the other issue with devices showing up in the UEFN editor and not in Creative edit?Normal - Inconsistences Between Creative Edit and UEFN - #3
Because for me I noticed the infinite Downloading issue around the same time I was having my own problems with inconsistencies when I deleted Building Props. Blocker - Can't test game for the past 3 days - Content Beacon and Infinite Downloading - #14
Might not be related because I think there are a lot of reasons why infinite Downloading happens but it’s interesting that you’re having two problems that I’ve had.
