Had a look at the code, it should be really easy to fix it so players respawn on auto-defrost.
I'm gonna try to get a hold of friagram and ask him to include it as a feature (not hard to do, I could even do it for him and send the update if he's too busy).
I could add it myself but if he's willing to add it officially it would make my life a lot easier since I wouldn't have to re-add it every time a new update comes out.
