So first of all. In order to use my avatar accross multiple comps should I link my G2G account to Steam account?

That hasn't helped for me.

Despite saving on G2G, and linking G2G/Steam, it still shows the default avatar when I launch on a different machine, and keeps it when I load a cloud save.

I have not found a way to get the second machine to display or use the avatar created and saved on the first.

Edit:  Copy/pasting the contents of the Documents/Humankind/Users/<hex string>/Registry.xml file from the machine with my avatar/persona into the same file on the other machine worked.
