Hi - I've noticed 2 things recently that I think are bugs. Apologies if my terminology below isn't quite accurate.
1. Whenever I log in on desktop web on the hentaiheroes.com site, the page refreshes with sound enabled and makes me log in a second time in order to actually log in.
A similar thing happens on Mobile Web on the hentaiheroes.com site where the page refreshes after I login, which shows the log in screen again with sound enabled. But it eventually does load the logged in page. It sits on the refreshed login page for about 5 seconds before it moves on to the authenticated site.
So on Desktop, I have to log in twice in order to actually log in. On Mobile, I only have to log in once, but it has an extra page between submitting the log in and actually getting logged in.
2. When I use the "Max Grade Up" function on a girl that has no affection from the view that has "My Inventory" at the top, when I then return back to the full harem list, the diamonds that let me switch between the different grade images on the girl I just maxed out are unclickable. I have to leave the Harem view and return in order to click the diamonds. This is happening on both Desktop and Mobile web as well.
