The quest currently begins when you find the toaster at GNR. If all the locations are already discovered you can finish the quest in 5-10 minutes.
It is just this simple. No new weapons or armor or anything like that. You do a few things and fix Three Dog's toaster.
There are no quest guides, the in-game notes should be enough. The rewards are small, don't worry about it being OP.
Future Plans: Have the quest start when the GNR story about the Megaton bomb is played (only if you disarmed the bomb.)
Compatibility:
CC Estates - Jennifer's House and Toastmasters will overlap some other doors.
Version 1.1 Changes
Fixed some typos
Adjusted scripts so quest completion should display before new objectives
Took a little info out of the quest messages. You need to read the in-quest notes.
