Answer:
Missed the opportunity to object based on inspections issues, and the contract is still in force.
Explanation:
There is a reason why the objection deadline exists; prior to that date the buyer can decide to not purchase the property without any negative consequences. But dates actually matter, and if the buyer didn't file an objection until that deadline, then the contact is enforceable. Once that date passes, they lost their opportunity to object the inspection item.
