Quick question, this can die as soon as someone clears this up for me.
(I can't find it covered in the Wiki.)
It's definitely been over 36 hours since I did my first leves... but when I try to select a new one, it asks me to cancel one I've got open to fit the new leve into my list.
Should I do this, or do they disappear automatically? I'm not really clear on how the system works, and I don't want to cancel them if they'll just disappear themselves. I note that some have a 0 star next to them, and some have 1 star. Is this relevant?
