If additional days are added to a ticket, does that mess up the FP's already made?

If a family member purchases tickets for only 2 park days, and at 60 days out FP's are made for those 2 days, but then at 15 days out they decide to add another day (1 day earlier) to the tickets, does anything happen to the original FP's that were made before the ticket change?

Just trying to think of everything before our 60 day mark. Thanks!

It should not mess up your FP's since you're adding another day instead of just starting a day early.

Nope.
