I'm sorry I couldn't make the images smaller ;-;
I noticed that the Defeat Murkwood Bosses thing was going up when my party simply cannot do that. The first image is a screenshot of a battle with a Consumed Keboko(it happened with a normal one too), and the second one I took after I reloaded the page. It shows 1/5 Defeat Murkwood Bosses when that simply... is not possible.
I'm terrible at phrasing things; normally I'd leave this for some other person to mention because I don't like dealing with images.
Sorry if this isn't a bug, but I'm pretty sure that shouldn't be happening so here I am
Have a nice day
