I have a question how many side quest will the final game have?
Also in the side quest to help the old man with the necromancer I don't know if its a glitch were you can start the quest before talking to the old man in the town
The side quests are not a big focal point tbh. Most towns have 1 or 2, and then every companion has 1 "companion quest". So all in all the final patch won't add that many, maybe 2 at most + Tabitha's quest.
I'll check the old man and his flags, but the fix will probably launch as part of v4 if one is needed.
