So my character Onion, level 5 rogue brought a friend to do the stonebuilder mansion quest in ticker square. Even though we are well within the level range and my character was the one to accept the quest and receive the quest invite token, the character himself was not added to the quest. I have checked my journal and the quest has not shown up there.
I could not use the quest token on myself either.
SFP was ig and was able to take the token and add me, and I'm pretty sure this is a really strange non replicable bug. Hopefully.
