S’ far as I can tell, you have to make sure the gene is active, and you can set a range for it as well as a check so it will stay within a certain boundary, but sometimes that doesn’t seem to really always work. There’s also setting a natural value and manipulating the return force, and messing with the return calculator. Though sometimes to get an effect you want, you may have to modify more than one gene. Since some genes are effected by the values of others or limited by them. Also, could be wrong but some values and genes set for characters are no longer used or replaced with different versions, butt he old code is still there, so changing those values won’t really do anything or cause conflicts with older systems in place but that depends what data packs you have, if any.
