@MostHost_LA Ooooof! It saved me from re-doing a lot of stuff. I took the Skeleton from Autosave and restored it, that solved the issue.
Thanks a lot bro! You are an angel! 
But I am afraid if I import the girl character, the Skeleton will again get spoiled. I shall try importing into a new project and migrating the asset to my project. I wish that will work.
