Greenskins

Greenskins (displayed as (Location Name): Greenskins) is a Minutemen radiant quest in Fallout 4.

Detailed walkthrough
Like other Minutemen quests, this quest can be periodically obtained while listening to Radio Freedom or when speaking to Preston Garvey. The Sole Survivor is informed of a settlement in need of assistance, with the details being available from the settlers themselves. Alternatively, the Sole Survivor may obtain the quest more directly by speaking to the settlers at a settlement that has not yet been unlocked.

For this quest, the settlers will direct the Sole Survivor to a nearby location that has been overrun by super mutants, asking that they be eliminated for the safety of the settlement. The Sole Survivor will need to travel to that location and eliminate the marked super mutants before returning to the settlement to report their success. Only mutants with a quest marker need to be killed in order to complete the quest.

After reporting the successful elimination of the mutants, the settler will express their gratitude towards the Minutemen. Settlements not yet allied with the Minutemen will pledge their support and become allied, allowing their Workshop to be used; the Sole Survivor will be rewarded with ~100 caps otherwise. If the quest was obtained directly from the settler, it will complete immediately at this point. If the quest was obtained from Preston Garvey or Radio Freedom, the Sole Survivor must instead return to Preston to turn in the quest.

If the Sole Survivor does not eliminate the Super Mutants and report their success within 7 days, the quest will fail and no reward will be given.

Bugs

 * The quest is radiant and prone to bugs. The most common bug affects super mutants: The quest will start as normal, but killing super mutants at the target location will not complete the objective, regardless of the counter updating or not. If the bug manifests, the quest arrow might not appear as well. Locations affected by this bug include Gwinnett Brewery, Breakheart Banks, Breakheart Banks, Faneuil Hall, and Scrap Palace. Somerville Place settlers appear to cause this bug to happen more often.
 * The bug can be fixed by using the console command, which will mark the super mutants as killed and activate completion dialogue with settlers.
 * The quest might not correctly activate the initial settler dialogue (eg. with Roger Warwick), making the quest impossible to complete.
 * The bug can fixed by using the console command, which will advance the quest without the need to go through dialogue.
 * In certain locations, NPCs might spawn in inaccessible locations (for instance, Roger Warwick at Warwick Homestead might spawn inside the water cistern.
 * If this happens and Warwick Homestead is a settlement, the player can resolve the issue by building wooden stairs going into the cistern, together with a warning bell. Using the ball and waiting for an in-game hour (using the Wait option) will cause the NPCs to spawn near the warning bell.
 * Otherwise, the player can use the console command ( for Roger Warwick) to teleport the NPC in question to the player's location.
