Zakko might be a potential glitch but i started a new game and dolly's quest wasn't triggered with the new content. Under active quests, it asks to meet her in the maternity ward and in the completed quests page, it has the new task saying she's not in the maternity ward, find her. Played it through until the end of this latest update just in case my overall progress was limiting this from triggering but yeah, it still didn't work.
Shouldn't be a bug. There was an old bug where if they player did/didn't do a certain thing in the hospital, the Dolly quest would bug out. That has been fixed. The debug room exists for people who ran into the bug before it was fixed.
In your case, provided you started a completely new game on the latest version v0.06a, you should be able to continue the quest by doing what the quest says. In this case we're asking for the player to ask around for her whereabouts. The dialogue does have MC mention Sweeps, the janitor, as the first person to ask. He's right outside the nursery in the maternity ward.
I've had 1 other report about someone starting a new game and it being glitched still, but they were in an older version unknowingly.
So I'd ask you to see if the quest progresses if you talk to the janitor, and check that you're on the latest version. If you were on an older version then get the newest version, and fix your save with the debug room. Thanks for the report.
