FC Member who bought a ticket for FC House left the FC

That sounds like something said prior to the automated lottery to deal with the limitations of said automation. Human involvement should afford them much more flexibility in how the issue that they admitted fault is addressed and they sound very committed to ensuring that FC's that won an FC plot get it. (And individuals that won a personal plot get their plot)

While it's not a guarantee it is also not hopeless.

That was actually part of the Lodestone announcement regarding the housing changes and they put it in bold red font to emphasize it.

Please note that all requirements listed above must be fulfilled at the time of both entry and purchase.

Human involvement can only go so far in bypassing how the system is programmed to operate. The GMs have even less ability since they are not programmers.

The entry did not belong to the FC. It belonged to the player - and the player decided they were no longer interested in helping the FC get their house. Are the GMs supposed to disrespect that player's decision? Nothing is owed the FC if a member was treated so badly they choose to leave.

At this point, the best hope for the OP's FC is that one of the other 4 entries they had was the winner.

Again, that's the initial announcement describing the requirements during normal operation of the system. That statement in particular does not apply to the current situation otherwise those that took their refunds would also become ineligible. The 0-bug was a major embarrassment and they are making every effort to correct it.

The GMs have even less ability since they are not programmers.

In any other industry that involves customer service they have a console or application that allows them to do things unavailable to players. Often there are tiers of access with wider permissions granted to higher seniority GM's. They should not need to be programmers to be able to do their job.

Even if whatever additional access the GM's have cannot adjust the results of the lottery Square has already committed programmer and IT resources to correcting the issue. The GM's don't need to be programmers because the actual programmers are involved.

At this point, the best hope for the OP's FC is that one of the other 4 entries they had was the winner.

Or that the system was designed to select another ticket if the winning ticket-holder is no longer eligible.
