The restart button is a piece of crap. Restart and reload are 2 different things. That useless button is just reloading the game.
Let's make this simple, the devs are not that smart, might have a problem to understand.:
I start a new world, chose my race and click to change the name (as I said, they are not smart, couldn't make it possible to remember the name of the player who use that account). While writing down the name, (another brain fart) the game flip, between races. Long story, short, instead of playing a dwarf, I ended up as an elf.
Being a normal person, with at least 2 functional neurons, I thought, ""no problem, I hit restart and fix it"... Don't need to tell you what happened, I am sure.
Now, there is the challenge for the devs: Do you want to be part of the smart people comunity?! FIX IT!
