As the topic says, Aloth's companion quest does not show up in my quest journal. I assume this is because I declined his offer to join when I first met him and only later invited him. I do not have any "before" savegames, so I didn't include any (nor the dxdiag file, because it is not that kind of bug). The only way I discovered that he actually had a quest is when he died and the message "Two-sided (or whatever his quest is called) failed" showed up. Note that I do not consider that a terrible bug because I will get rid of him as soon as I find someone to replace him as the sixth group member anyway, but it IS a bug, so there.

There is a companion quest for Aloth? I had no idea!

 

I saw that there was one for Eder but I had no idea Aloth had one as well.... Is it triggerred later, I wonder?

 

As opposed to you, I did recruit him when he first oferred so I am not sure if this is a timing issue...

I too noticed the "quest has failed" thing when Aloth one accidentally died. Is this a bug or do we just acquire his quest later? I assume bug because it seems you get the companion quests soon after they join.
