What error is this log?
It looks like a bug in 3.8.79 when duplicating a skin.
If you must use 3.8, then use the latest, which is 3.8.99. There is no reason to use 3.8.79.
Ideally you use a more modern version, as we don't do bug fixes anymore to such old versions. 3.8 is very old. 4.1 is the latest, and 4.2 is currently in beta. 4.2 has physics!
