Hello everyone, I've seen there are lots of the same post and I know its a known issue but still I wanted to post my problem here, I was swapping between characters, respecing them and switching gears for min/maxing, than I noticed 2 of my companions weren't on the Roster. Kana and Sagani. Interesting thing is, they are in the game, not completely disappeared but they are waiting at the exact same locations where I found them the first time (Sagani at Woodend Plains and Kana at Caed Nua.) I can speak to them and they seem to keep their gear, but there is no way I can add them back to my party cause I can only see Eder on my Roster, even my custom made Rogue is missing. Is this also a part of the problems to be patched in the future? I hope it is, because I don't want to start the whole game again just to keep them in my party, any workaround to get them back in the Roster? Thank you,
