thanks for the info i found the shackles and learned that shortly after making this post i read about them but couldn't find or craft them for some reason even after making the prison/jail cells, work shop, and binding cells. i ended up putting people in all of these and after a while i was able to do it not sure if the workers where the cause of it but i can do it now
there now seems to be another hidden "tech requirement" of some sort. i dont know if it is having research, or having a servant with specific traits, of a specific race, another dungeon room, or a level threshold is the trigger.
at one point, i had ~150 scrap cloth, but only the option to craft bandages. shackles only became available ~2 weeks later. i cannot tell what the actual trigger was, only that at one time i could not craft them, then i could.
shackles wasent the only crafted item this applied to, either. i couldent make lavish meals or exp crystals, either. until like day 60, my available crafting was only demonic brew and bandages, despite having the materials for p much everything else you can craft in the game.
