I've hit many jackpots in the 40k to 100k range and never had anyone ever reset my machine.
I've either played it off or refused to play it off.
Must be a per property thing or something new.
In some places, that jackpot wouldn't even be a hand pay if you're on Fast Pay.
In other places, like the El Cortel they take the hard drive to the back room and check it for a 10k or higher jackpot lol.
If you hit a large jackpot in some downtown properties, on graveyard, they literally make you wait till the day shift Mechanics/IT Guys come in.
That's a pain, IMO.
