Thanks for the edit! Glad it was a false alarm! LOL
I am having this issue and no clue why. Redirecotrs all fixed up, proper migration as done 1000s of time. Same engine version. Yet only folders and no actual content. However in Windows Explore it looks as thou it is an identical project.
I have had several reach out to me on this same issue over the past few weeks so I am wondering, why now? & what has changed? I find this to be very curious as well as frustrating for new and old users.
Yet to get to the bottom of this, if/when I do, will update here.
