Kingmaker for 5ed

[numero42]

i'm trying to fully convert kingmaker for 5ed and i found a problem with realm management with the updated rules. Updated Rules go well with the 5ed but when it comes to magical objects create confusion. The 5th in fact does not have a system of buying and selling items, and the kingdom management rules instead include buildings that increase the level of the magical items available (common in pathfinder 2).
Has anyone found a way to handle this?
Thanks!!!
