Not a bug, but if you continuously fail a boss you can setup meowth or persian to get an insane amount of many especially if you also add ditto as meowth or persian, so maybe lower it from 10% on bosses also to only 1% to make it more balanced,
I know, I joked on Discord that I was going to nerf it, and everyone told me not to even think about it hahaha.
not true bosses appear very rarely and the money it takes just to buy a new pokemon after unlocking 40/70+ is insane literally.
i have 740 million rn if you have auto retry on it keeps sending the boss over and over again. only took a few hours
