Couple issues; Goblins getting stuck in the walls and beds. No option to cancel a blueprint once it's laid down. So far, it seems like an interesting concept so I'd say keep it up!
The goblins are still getting stuck in the walls. If a wall is constructed with another goblin standing in that same tile, they get trapped. The same for beds, as well. I wonder if there is anything that could "kick" them off a blocked tile? Like, shift them a space over so that they don't end up getting stuck in an impassable tile.
