So I am now about 16 hours into the game, currently travelling through the Underdark.
I have realised that it is not right for me to NOT encounter several companions - Lae’zel, Wyll and Karlach, so yes, I have searched Google to check their locations. I hate to do this, but I also hate those guys I have to travel with, I wanted Lae’zel and Karlach in my team since the announcement, and I also believe Wyll would be fine addition to them. So yeah, I googled them before I've finished the game.
I got back to Wyll and Karlach with no problems, despite I have already finished all quests related to Emerald Grove.

However *spoilers ahead* I am not able to find Lae’zel. Her cage is broken and tieflings are dead *spoilers end* How do I found her? Is there some cheat-code to bring her back into the game if she was somehow deleted?

I also have a problem with Halsin. He is chilling in my camp, but he has no dialogue options to add him to the party. Is this some kind of bug? O did he get upset *spoilers ahead* that I refused sex with him? lol *spoilers end* He has weird dialogue option, something about my "strange behaviour during tieflings party". I do not remember any strange behaviour from my side, also if chosen this dialogue doesn't make clear what it's about, but Halsin confirms he is not angry at anything. But adding him to a party option doesn't appear either.
