For some reason the memory lock puzzle to the candy machine keeps messing up. I know I'm pressing the right keys, but I often get interrupted before I can press the next button and it keeps moving on in the game before I'm finished inputting the sequence, or it kicks me out because I supposedly pressed the wrong button and have to start over - and I didn't. I know I was right.

What could be going on?

I have no idea what's going on. The only thing I am reading oniine is that if you wait longer than three seconds to click a button that the lock resets. Maybe someone else who has played the game more recently will have a suggestion for you.

I agree with what Marian has said. I know in my playthroughs, if I've been slow to click, it's acted like I clicked the wrong one
