The Drunken Lizard Pub

So I was doing a new playthrough and I forgot to talk to shelta marie before going to old moonrise.

now I can't get her quest. ugh.

I tried to add the sealed letter to my inventory... but unfortunately without the quest being coded as begun.. no dice.

I already did SOOOOO much and only quicksaved.. don't really want to clear out all the places again with this character/

is there a way to add a sealed letter quest via codes or items?
