i tried all that, she was in her "casual" outfit instead of her highway outfit, and normally when you meet he she stays there but when i did she vanished again and if i tried to "meet her" again it just kept repeating the "oh wait is that mira" stuff, i tried that on day 4, day 10, day 16 and day 26 all with different stages of friendship lvl and it happened all the time.
(im speaking about the "pepper spray route" btw i saved her once the regular way but it change her and cass's character iirc)
