Character melt not working

Sometimes it takes a few seconds for the time left on the carbonite melt to appear. I'm used to that.Today, I can't make it work. I've launched the game several times over the course of the day to find no time indication on the carbonite melt icon. It's stuck with the circle/slanted line symbol.I've done the usual stuff: removed this and other apps from memory, restarted the iPhone, etc.Anyone else?
