This is likely the wrong section to be asking and someone probably addressed it somewhere but after looking for quite some time, I'm just gonna take the direct approach (with any flak that comes from not trying harder to find the answer).

I was trying to AW Katie (don't question/criticize why, was just a matter of "wanted to try") so I maxed her affection and level, got an awakening fairy, got my Soldier Chief orb ready, and figured I could just test my old Phyllis and use my old Harissa (still working on the barbarian part).

Problem is, even though I managed to prep my awakening fairy just fine, both Phyllis and Harissa are greyed out when I try to select them to their respective slots. Phyllis, I'd understand since she's organized into one of my parties but Harissa isn't, and for that matter it's the same for the non-cc'd gold rogue types I have.

I'm wondering if there's any specific condition pertaining to obtainable stats such as level or affection that could effectively disqualify a silver/gold unit from being used as AW material. I have to wonder if I missed anything or unintentionally made it so that I wouldn't be able to fodder them at this point.

^Right when I finished writing this post, I looked at my unit list and realized my own derpage: I locked both silvers and my gold rogues so naturally if I appeared to have no intention to consume them for anything, the system wouldn't let me AW fodder them.

Seeing as I've already gone this far, I may as well ask anyways and then put up the light warning that if you plan to use your old units for AW fodder, consider if they're in locked status to avoid having the same confusion and derpage I went through.
