I did Fixup before and after deletion. I can reproduce this bug. When i use ThirdPerson-C+±Template and move textures folder to another location, Textures folder stays at its location and i create a new folder with moved assets at desired location. Its weird. And i dont know how to delete Textures folder at old location.
Maybe UE4 needs some rights? Maybe he cant delete this stuff? Or a problem with redirectors?
I think it has something to do with that: redirectors doesnt disappear and content-explorer shows all folders with files. And i cant see redirectors in content browser. result is, that i have old empty folders, which reappear every time UE4 checks project folder structure.
Or maybe it has something to do with blueprints/materials, all stuff that needs to be compiled. redirector doesnt disappear because blueprint only knows old location?
Maybe move this to bug reports section?
