I recently discovered Bunker Hill and have encountered several dialogue bugs when it comes to speech checks and increasing rewards for quests given by the merchants there. The entire increased rewards option for these merchants is broken, because even if you talk your way into the highest level reward, they still reward you with the minimal cap reward they offer you to begin with. I have replicated the problem every single time (by reloading the save). Here is what happens:
1) talk to either of the two merchants offering quests (jobs)
2) continue to ask for more caps using the left-most option (square button on PS4)
3) once you have reached the highest speech check for the max amount of caps, the dialogue option to ask for more caps is still there and turns green (from yellow, orange, or red; depending on difficulty of the check)
4) if you press that speech option again, the one that asks for more caps, you automatically fail, although it doesn't say that you have failed, and the NPC responds with the basic, canned response of denying you more caps and goes back to the default offer they gave you, regardless of the fact that you have already talked them into several better offers!
Lastly, but probably MOST importantly, when you complete the quest, they still give you the minimal amount of caps!!! Basically, the reward dialogue with merchants' jobs in Bunker Hill is broken!
Please fix. It's a small annoyance, but definitely should have been addressed in QA stage.
