[2020] Mon Mothma gear bug? MK5 Medpac in shop does not show it as needed by favorited Mon Mothma when she does in fact need it.

If a character is unable to equip a piece of gear they won't be listed and the gear won't have the favorite tag on it. This is working as intended to avoid confusion. As for the yellow warning, that should appear on the main gear piece but not on the pieces that you need to craft the piece.
