caesars blackjack cashier locked after one larger double down win.

Had a weird one tonight - was playing blackjack steady and nothing out of the ordinary, then hit a nice double down, nothing insane, just a good win. Cashed out, then my cashier option goes gray and says locked for review. Never seen that after a double before. I usually keep my bets in the same range and don't go wild.

Figured maybe they’re just scanning for bonus abuse or weird betting patterns. Makes me wish I just stuck with my normal slow style, because I never have issues when I keep it real basic. Curious if others have had this lately.
