Confirming and updating quests in journal:
1) "Finding Emmie"
Problem is I've picked "pet pal" only after fight with Alexander (got lvl 8) and seeking all nooks and crannies, pets in this case got the quest from Buddy. At that moment all dogs in dungeon were dead, so no way to solve the quest. The game is not checking the status of that location, there should be an option to tell Buddy that his mate is dead or something like that.
2) "The Imprisoned Elf"
Done everything I could, Amyro is free, the following quest is taken (The Tribe of Saheila)
But still the quest is glitched.
3) "The Tribe of Saheila"
No way to complete it without leaving the island - that's a mistake in game design.
4) "The Arena of Fort Joy"
No option to choose anybody else after winning the first fight. This is frustrating. Also I'm going through content solo, without any npcs, and there is only two option before fight: "my mates will help" and "I don't want to fight", weird isn't it?
It's easy to make a check if player has no mates!
5) "Withermoore's Soul Jar"
Quest is not closed after dealing with the Withermoore's soul jar.
If it's an issue regarding this info: Lord Withermoore will come back to you one last time to unlock the barrier door inside Braccus Rex fortress and thus mark the quest as complete
I've opened that barrier with the source, saw no Withermoore, quest is not closed.
6) "Every Mother's Nightmare"
Same thing as with "The Tribe of Saheila" - game design mistake. I can get it when it's only option for free exp. - to talk with 2 npcs nearby, but if there is Emma's ghost, but in other, non reachable location that's wrong!
About "The Purged Dragon" quest:
I chose to free the dragon, but it's really wrong when Slane is returning his favor in simple situation - I was merely purging the Shriekers, everything was under control and then the dragon kills the rest of Shriekers closing the quest... Why? Regarding this the only reasonable option is to kill Slane.
It took me about 30 hours to find all these things, can't believe that QA had no problems with that either.
Hopefully Larian devs will draw their attention to these issues to make the game better.
