Separate issue: I know I'm not doing anything wrong, but it feels like I am. I've done something like 20-25 Lives and can't trigger a Keep to save my life. I'm using a member's personal song (Haruka/GO MY WAY!!) and I'm using a set of matching accessories to boost lucky star gain. I know we already cleared it up, but I'm seriously starting to wonder if it shows up on the week I perform the Live or the week after, because this is ridiculous. But I'm trusting you guys that it happens on the week I perform the Live.
Welcome to pain, it's really awful. I'm in the same rut currently, though only up to the 15th attempt. It's not a personal song (Jibun REST@RT), but Lucky Stars still pop up pretty often. Out of all the sales statuses I've gone for in Hyper, Keep seems to be pretty difficult to activate. Granted I've not forced a Super Break before in Hyper, and it sounds even rarer according to posts in this thread.
I've only had this much trouble this time around though. Before this I was able to get a Keep with under 10 attempts. The accessory sets are a pain, I didn't use them until Hyper. At times it's irritating to use one and only a small amount of Lucky Stars pop up. Though that's not an indication of success, as I've had many pop up with no sales state change where just a few otherwise did the trick.
Chihaya also can't make up her mind if she likes the Pac-Man set or not. Mami and Makoto seem to like it, so too bad... you're wearing it.
It does indeed appear on the same week. Stay at it, or try a different tactic in a later week if it grates too much on your nerves.
EDIT: Totally unrelated, but I'll need it for the next song: When you're doing Quintet Lives, what affects the intimacy of the available guests? It seems like the only ones above the lowest level are Ritsuko, Ryuugu Komachi, and the idols I used in my unit in the previous game.
I think it's how often you've produced the idol (be it as leader or support) and how often they've been invited in previous units. Who's in the unit does to a degree as well it seems. When using Yayoi for the first time Iori seemed to have around 10 invites on her tally when she was made available. This unit is the first time I've had pink faces with invites and one of them hasn't been used all that much (in a unit or just simply invited). I've only completed the Extra Episodes once each, so I'm unsure how much that will affect invites.
I don't have any blue statuses anymore, so as time goes on it gets much easier to invite anyone it seems.
As for the light, could it indicate that you have Voltage you couldn't fill prior to the song ending? I'm just guessing, I really don't know. I've seen it before as well, I'm just at a loss as to what it may specifically mean.
