Raider Troubles

Raider Troubles at (location) is a Minutemen radiant quest in Fallout 4. This quest can be started randomly when speaking to Preston Garvey or listening to Radio Freedom. If a settlement hasn't been unlocked yet, this quest may be started by speaking to a settler at that location and it will unlock the settlement.

Failure to kill the targeted raider settler in a timely manner will result in the failure of the quest.

Bugs

 * No quest marker will appear on raiders inside Back Street Apparel, quest would not update despite clearing Backstreet Apparel (the usual target raider is situated in the ground level back room with the steamer trunk). Workarounds for finishing this quest are (as with similar Greenskins and Ghoul Problem quests) either killing the quest giving settler or waiting out until the timer runs out, though both ways will fail the quest.
 * Should you have to help Covenant after completing Human Error and leaving the citizens alive, Jacob Orden will be the NPC to speak to, only he won't have any voice acting. After you clear the raiders, you will not be able to turn in the quest, as he will just comment on your completion of Human Error.
 * The option to say that the targeted location has been previously cleared won't appear, along with the quest marker, preventing the quest completion. Clearing the location anyways won't fix this.
