It is possible for an active auction to close at a price lower than the newly increased reserve price. This is undesirable especially when preventing a Noun auctioned off at the lower than expected price could be out of control in a bear market. Consider adding a check alleging that the contract balance needing to exceed the reserve price. Else, the last bidder will be refunded prior to having the Noun burned. Heres a refactored code logic that will take care of the suggestion.
