I'd like to propose that you allow steel crucibles to be built inside houses, be it only top floors for magical ventilation or cellars in the idea that no one would go down there too often, idk.
The reasoning behind this is that past the first palibasher in any one world iteration, new camps will be unable to evade the armies of scouts a raider faction can dish out. If they want a quiet medium sized claim any attempt at brickwalling will be visible and their steel sought after. Mind you my steel got stolen only 5 hours after its completion timer finished , so i've no clue just how frequent these scouting passes are, but it seems to be trending and is quite harsh on mid-game to late game new camps if they can't so much as prepare for a wall in peace without being squashed way too easily.
Ideally the siege patch will help fix some of these issues, I would hope , but in the meanwhile raiders seem to be picking everyone clean in anticipation of the siege patch. At the very least a nice change letting people be discrete with their valuables would be nice.
