Butcher's Bill

Butcher's Bill is a Railroad side quest in Fallout 4.

Quick walkthrough

 * 1) Go to the dead drop.
 * 2) Determine status of Augusta safehouse.
 * 3) Report back to Doctor Carrington.

Detailed walkthrough

 * 1) On completion of Boston After Dark Carrington mentions concerns about the status of a couple of safehouses. The Railroad was struck simultaneously at many of their locations when The Switchboard fell.
 * 2) Head to the dead drop, its location varies and is determined by the radiant quest system. Take the holotape from the container and play it.
 * 3) Head to Kendall Hospital and make the way inside, exploring the safehouse while keeping watch for traps and raiders until the elevator is reached.
 * 4) After the elevator follow the path until reaching the large, open room.  The quest marker is a floor down, avoid or kill the raiders, then listen to the report.
 * 5) Drop down to the bottom floor, kill a deathclaw, flip the circuit breaker in the southeastern corner, then head out.
 * 6) Alternatively—flip the circuit breaker, run to the now-energized door, push the button and outrun deathclaw to exit.
 * 7) Return to HQ and turn in the quest.

Bugs
The dead drop may not appear at the noted location. Possible fix includes progressing through other Railroad missions until given another safe-house mission. This may make the dead drop appear with both missions packages. It can also be fixed via console commands on PC: Bug can be avoided by not quick traveling and going out the escape way mentioned by the doctor.
 * Add the note found in the dead drop:
 * Set the current objective as complete:
