What process did you use to retrieve the copy of ASP_Character? Did you copy the file from the project folder or did you migrate it into your project from within the editor? Are you able to open ASP_Character in the original project before moving it to your project? Also, did you change anything about ASP_Character or it’s references after moving it to your project (add any nodes to cast to and/or from ASP_Character or reference it in another blueprint)?
