We have now had at least 3 instances where customers accidentally purchased tickets to events that occurred in the past. We have reached out to your team and been told there is apparently no way to stop this from happening other than archiving the whole event bucket. Since we still have upcoming events in the same bucket where this is occurring, we can not archive it. Super annoying for both us and the customers to deal with! Pretty please find a way to ensure people with old links, etc cannot buy tickets to events which have occurred in the past.
