The Crafteria (Default Relaxation 1x1, 2x2, 3x3, Interior)
A community workshop with various workbenches. They are all linked to the main workshop, and usually gain all vanilla workbenches, plus a custom "Utility" and "Electronics" workbench by L3. Cooking and Chemistry are often combined into one single workbench. Utility and Electronics are combined into one in the 1x1 and Interior versions.
The 1x1 version never gains a Power Armor workbench. It is too small to house it.
The 3x3 version gains the Power Armor workbench at L2, and gains a Robot Workbench at L3. If you don't have Automatron, it will spawn an unusable fake instead.
The unusable fake will also be spawned if you haven't finished "A New Threat" yet. Supposedly, it could cause issues otherwise. Refresh the plot after finishing it, if it reached L3 before that.
