So I use Google Chrome to surf the site. Version 131.0.6778.140 (Official Build) (64-bit)

I battled Sir Buckley the Bold and defeated him. On the You Won page, there are three buttons: Fight This Opponent Again, Choose Different Weapons, and Back To Challenge Page If I choose the Fight This Opponent Again button, I get taken to an error page that says, "Oh No! You must select at least 2 weapons!" But I used three weapons in battle, and there's no option to re-select the weapons you used in the last battle nor will they roll over. I have to Choose Different Weapons and then just re-click the weapons I used last time.

ah, didn't know they HAD to be in a set to reuse them. Thank you.
