What do you mean?
Whenever you submit to a chain, it gives you a new one. If you leave the site, such as going to bed or even giving up, it doesn't pass on the new chain to someone else. As such, you can basically forget over an entire chain unintentionally. :(
The only solution I have is playing until a "We want a new chain!" but that takes forever sometimes, and I feel too strongly guilty just leaving a chain stuck even for a day (because I might not be back for weeks).
