Wrong FT Admininstration

[Spence]

A1 drives. Fouled while shooting. Ball goes in. Calling official didn't see the ball go in. Reports foul and says " 2 shots."

A1 misses first shot. A2 rebounds the miss and sticks it in. B team players didn't go after the miss because they were told 2 shots. Officials blow whistle and remind players it's "2 shots." 2nd shot is made. B inbounds the ball. Play ultimately ends when a timeout is called.

At that point officials get together to discuss.

It's no longer correctable due to the ball becoming dead after it went live, correct?

Note: This was the first play of the game.

Anything to be done here or just play on? Even if the officials said during the timeout that the shot went in it's too late to count it, correct?
