External reference and viewport camera issue in 4.9/4.9.1

I updated to 4.9 and when I made a copy of my project and tried loading my level there was about 500 external reference errors. Then I updated to 4.9.1 and I still had the reference errors and now for some reason the camera in editor mode just automatically drifts down to the floor, if I try to adjust it I just keep fighting the moving camera in the viewport. I’ve migrated my projects starting from 4.2 and had never had a reference problem or the camera issue, I always make a copy. I recently changed my UE install location from my C drive to my D due to space issues but I still had no trouble after doing that in 4.8. Any help would be fantastic, thanks!

Hi FlickNolis,

Do you have any x input controllers plugged into your PC? If so the moving camera is probably caused by that and is a known issue. the external reference errors sound very similar to a recently reported issue, does this look similar?
