Currently, anything you do after midnight that causes the graph to refresh that isn't "add a large enough data point" can cause derailment. Just now I went to the website to add a data point to a goal that was about to derail, noted my target needed to be pushed back a week, and used the road dial before I sent the data. This refreshed the graph and derailed me. This is a perverse disincentive. I shouldn't be charged money for adjusting my goal without warning. The fix is simple: any action taken on the website that would cause a derailment should cause a popup warning to appear before allowing the action to go through. "Doing this could cause you to derail immediately. Continue?" This warning should at least cover: hitting refresh, adjusting the road dial, entering a data point that is insufficient to prevent derailment (perhaps because it has the wrong day set).
