I eventually found a solution:
- inside unreal, copy the assets to another folder inside the unreal project
- close unreal
- delete the
saved
andintermediate
folders - reopen unreal
- fix redirectors
- close unreal
- commit to perforce
- move the files back to their original location
It wasn’t giving me issues after all of that. I saw somewhere else that moving files forces unreal to fix redirectors in cases where it won’t otherwise, that’s what ended up solving this for me.
