I don't know what kind of sugar you're talking about, if it's milk sugar. Fruit candies and other quality may be affected, but as long as the time is not very long should not be a problem. You can put them in the freezer and eat them after they've been molded. It's not bad. If you're talking about honey, don't worry about it. Because the only food that doesn't go bad is honey. Don't believe this is what I read on qq news.
