Two Tungsinn quests, can I fix them via the console?

[Azira]

The quests in question are Fly the Banner and Luckless Hunter

I killed Brokentooth before I got the Fly the Banner quest. Now I'm stuck with the quest banner in the inventory and an empty castle which offers me no options to interact the banner with it.

As to the Luckless Hunter quest, I killed the black unicorn, yet got no quest item, leaving that quest also unresolvable.

I know the first quest was supposedly fixed in a recent update, but I've spent 89 hours playing this game already, don't feel like starting over for a few quests. Is there a way to fix them using the console? Or at least, get the quest rewards (spell scrolls "Life Light" and "Hel the Messenger") for the A star is born quest, which otherwise hinges on the Fly the Banner quest?
Possibly a console command to get the princess dress quest item?

Otherwise, I'm loving the game, which should be evident from the amount of time put in it. Note, due to having small children, I have at times had to leave the keyboard with the game running in the backgroun, so the 89 hours haven't been spent actually playing the game. I believe the correct amount of time to be close to 70 hours, but that is still much, much more than I'm prepared to go through again, just to see these two new spells.

Please, spoil me.
