Here's actually the reason we have this messhttps://www.warzone.com/Forum/249786-warlight-unity-alpha-now-available?Offset=180
"The commit button is in a dangerous position, if you are moving through phases using the mouse, you might accidentally click on it and make the turn advance - I think you should click it twice with the mouse for the turn to advance, the first time it should say "click again to commit"

If you played the earlier Unity versions, you'll remember that's exactly how it used to work.
The confirmation phase is a tough subject. It makes sense in multi-player, but not so much in single-player where people expect games to go faster. One complaint I get a *ton* from new players is that there's too much clicking. I see new players always complain that they have to click twice to commit orders. It causes a lot of negative reviews. So there's no more confirmation phase. If it's really a problem for you, I recommend never clicking up there and just using the hotkeys, or train yourself to be careful where you click.
