I'd like to point out that this needs to be changed at the loading screen or at the menu but before the game is started. Changing it in-game or after a game has already been finished will not work.

Edit: This apparently applies to medal swaps, too. I did a medal swap for killing boss one and getting 50 candies in survival, then tried to change the swap to the 150 candy medal and killed the first boss again, and didn't get the medal. The game needs to be reloaded after each medal swap is completed.

It's not like that's something that applies to every single game.

I've not had that problem with any game; I've almost always been able to change AOBs after it had loaded and even in-game... I understand it's a good habit to get into changing AOBs before loading, but sometimes the AOB isn't present until after the game starts. I dunno, that's just my experience.

I'll have another look...

Ah, I see...Sorry, got a little overzealous.
