Shields are made to size of the craftsman, so gear made by larger workers scales up by default since its armor and not a weapon. Falling in the same category to the things that happen to clothing when the same design is passed between. Without a 'd'etail it'll always be made to fit the wearer.
"Major bug fixes
Fixed w.g. crash related to dark fortress civs having fixed positions not held by demons"
I havn't had the time to check this yet, but does this finally fix and once again have our own positions without the crashing issue once again?
The demon in question seemed to be pretty chill and content to enjoy life by competing in wrestling matches and attending geography lectures. I don't know what's causing this, but he seemed to be a master of nothing and does nothing that demons usually do. More than that, the world is devoid of goblins. More research required?
Already all powerful in a dwarven civilization which prizes itself on different values to goblins, so by extent it seems the demon does things the dwarven orderly way, while the monarch still pulls the strings of power to stop unwanted wars.
Probably a bug manifested in some way to have two hardcoded monarchs at once (they both allocate personal advisors and such) but it does make the civs playable because experimenter leaders will CTD without the other monarch there. So having two leaders who in theory powershare (and the demon dies off and becomes replaced in the council of 2 civ leaders) maintains equilibrium.
Pre 47.05, [POSITION:MONARCH] over dark sites used to be one and the same, it'd allocate to them, but nobody knows what the new token for demons would be. A likely rumor from uncompressed saves is that it could be now hardcoded to [POSITION:CUSTOM_LAW_GIVER] but that can as easily just be a catch-all based on site type for mead hall lords.
