If a bug is labeled as just 360 that just means its confirmed for 360 it still might happen on other systems, like the list says if dismissed instead of going home she wanders and often won't be recruitable again. Going back to a save from before dismissing her would be best if you can otherwise look around for her starting where you dismissed, you could try turning off any quests in your journal marking Darklight on the map and using clairvoyance to try and follow her route.
