I'm a bit curious about something that bugs me and nips at my ear every time I see it. I have all 4* equips, a helmet, armor, sword, gun, and shield at the moment I'm posting this. I've already passed Hall of Heroes 6-2, but something doesn't appear right; I can't access the 7-1 missions. This is very odd, considering I already have tier 3 clearance, but I am unable to do any 7-1 missions. It bugs me considering I need rank 8-1 to equip 5* equips.
*Edit*
Wow. I'm an idiot. Didn't realize I didn't do Whipping and Mishandling. Well, I guess this one's going into the Graveyard.
This belongs in Bug Issues please.
As for your question, have you done the other missions other than Hall of Heroes? That might be the problem.
