Integrates into the base game in an immersive/lore-friendly way. You can gain access to the workshop (legitimately) by completing the quest Order Up. How you solve it is up to you; you can make everyone friends, kill Wolfgang and Simone, kill Trudy and Patrick, kill everyone, whatever, but your choices will affect who you gain as special settlers, if anyone, as well as your little ending message (or lack thereof). I wanted a Drumlin Diner settlement mod that felt like it was truly a part of the base game.

If you've already completed the associated quest, the workshop will automatically unlock for you next time you load your save, along with granting any special settlers if your choices made you eligible for them.

Features include:

• Aforementioned quest integration!
• A new sleep area for settlers, made out of workshop scrappable parts so you can get rid of it if you don't like it, and the parts that aren't vanilla-scrappable are correctly linked to parts that are, so they will be scrapped if you scrap the main structures.
• Beds that are hooked up to the workshop from the start.
• Almost two full cells of building and sandboxing space.
• Properly and correctly registered workshop that you can send settlers to and from.
• If alive at the end of the quest, Trudy will take up her usual spot and provide significant vendor income to the settlement.
• If alive at the end of the quest, Wolfgang will assign to his new shop counter and provide significant vendor income to the settlement.
• If alive at the end of the quest, Patrick will be assigned to take stock inventory, which provides food and water.
• If alive at the end of the quest, Simone will be assigned to patrolling which provides safety.
• Simone provides bonus defense to the settlement.
• Trudy and Wolfgang will both continue to be able to sell to you from their special inventories as normal.
• Items in Drumlin Diner will no longer be marked as stealing once you have finished the quest.
• Accurate-ish workshop borders. (build area is accurate, but borders are not flush with the ground at all points)
• Workshop will not recruit Brahmin. Trudy runs a tight ship at the Diner.
• Moveable bespoke workshop so you can place it anywhere you'd prefer.
• As usual, high quality assured. Workshop reports in screenshots!
  

Notes:

• Trudy, Patrick, Wolfgang and Simone cannot be commanded and moved because this mod is intended to be immersive and feel like it was a part of the game all along. They aren't interested in taking orders from the Sole Survivor, and Drumlin Diner was theirs before it was ever yours. I have made work objects for them that provide a great benefit as a way to off-set this, so your trade for being unable to assign them is that they have better jobs than if you were able to assign them. If you really hate this, your options are either: run console commands on them to change this, use the optional patch at the same time as installing the main mod, or kill them. More information in the FAQ & Troubleshooting article.
• When taking control of the workshop for the first time, if any of the NPCs are alive and have joined the settlement, you'll notice a dip in happiness. This isn't a bug, it's normal behaviour, as 2-4 settlers have joined an underdeveloped settlement at once. Build some nice stuff for them, and they'll be happy before long. You cannot lose control of this particular settlement due to low happiness, so you won't be penalized.
• Due to NPCs being called to evaluate their AI Packages at virtually the same moment they get added to the settlement, you may notice them get momentarily confused if you're in the cell at the same time the workshop unlocks. They'll sort themselves out if you give them a few seconds, but if you have too many processes going on in your game and the NPCs can't catch up, try fast travelling away and then back again.
  

I highly recommend reading the FAQ & Troubleshooting article if you have any questions or run into issues. Scripts can be fickle, and if you have a lot running in your game or the game isn't reading the BA2, you can run into problems. Be sure to check there for answers to common questions.

Requirements:
Base game (nextgen update highly recommended. As of 1.1.1, it shouldn't be required, but it is extremely recommended. I can't actually help with any oldgen issues.)

Highly recommended:
Scrap Just A Bit More Stuff

Installation:
Any time, mod manager recommended. Like any other settlement mod, as close to the end of your load order as possible.

Compatibility:
Obviously will conflict with anything and everything that edits the Drumlin cell, or the wilderness cell that the attached car park is in. The level of conflict kind of depends on what you're running, but it's a popular area for mods so just pay attention to what you're installing and decide what you want to experience in that area personally.
This does, naturally, contain NPC edits to Trudy, Patrick, Wolfgang and Simone. If you have other mods that affect the same NPCs, they will not be compatible.

Uninstalling:
There is absolutely NO way to safely uninstall a settlement mod once you've added it, so don't do this! Make sure you drop a hard save before installing the mod, give it a try, and if you don't like it or encounter an issue, revert to the clean save.
