Been having various issues today. It started with not being able to equip moves on fighters. Well I can equip them but the game gets stuck on a connecting screen when I try to leave the fighters stat menu and after restarting the game it still has the old moveset. At one point the app got stuck on another connecting screen after I won a fight in the origin story for Valentine. It came with the error code 3.UDE.20 I'm sure this isn't a huge issue, just server server issues like the app was saying, but after that had happened I went to check the skill tree for the Valentine I'd been using and all the unlockable node sections that I'd unlocked earlier were locked up again. It hasn't reset itself or reverted to an earlier state because some of the basic individual nodes are still unlocked and the keys, skill points and coins used for them haven't returned. I have a few silver fighters that I'd been powering up around the same time which I'm slightly more concerned about, although I'm not sure whether or not they've been affected because i wasn't paying as close attention to the key counts and amount of skill points for them.
