Invsee character over run

[Darnation]

Server crashed while I was /invsee and my characters skin colour got changed to something I don't like and some items got overrun or deleted. My single-player character got overrun by the original character without the skin or item change. We are playing on 1.4 so I understand if it is because of instability. Any way to revert my character back to what it was because I have the file of the original character? Thank you
