I accidentally merged the default third person skeleton with a custom character i made and it messed up the default skeleton. How do i reset it back or undo this somehow?

I know this was a while ago, but I found a good solution to help with messed up skeletons. ThompsonN13 above said to go to the add button and reimport the Third Person Assets, however this might not necessarily work. The best way I could find how to properly fix/reset the skeleton is to first rename the messed up skeleton and let it adjust all of it’s references. THEN go and add the button and then an SK_Skeleton will be there with the clean skeleton. You can then go in and reroute the references by clicking on both skeletons and clicking “replace references” and delete the bad skeleton. Hope this might help someone!
