I know you haven't asked for my reasoning, but here it is anyway.
Basically, I think the original personality was, what it said when you pick it, entirely cosmetic. It affected character speech, paper doll pose and that's almost it. With the new revamp it actually is a part of character as their build. I'd say the easiest way to correct it is to mod the stat bonuses for them, which is pretty easy to do.

Yeah, could understand the reasoning behind wanting to make it do something. Just think it actually debuffing you makes choosing one you like instead of one you want for the character an issue. The kind buff, for example, I liked. Made sense, gives you slight buff that may not affect character its on, but if it doesn't, oh well. Doesn't hurt you not having the buff. Whereas an actual debuff can actually hurt the character. Since shy raises matk, can understand wanting to lower atk as a counter, but wondering if it may not be better choice to just lower the bonus and remove the debuff instead, because then its more like the kind one. That way having a certain personality CAN help slightly, but it doesn't cause problems if you want a different one.
As for modding it, I've no idea how to mod this game. I can install mods, but not make them. Only seems easy if you know coding. Unless you mean using json editor on save file to alter bonuses? That at least I know :D
I wanted to make personalities have bigger impact, so if we just add +10% matk its not really something to consider compared to bigger bonus.
Game scripts are not encoded. To change it you'd go to Effects.gd file and search for e_person_shy entry, after which its pretty much same as working with json.
Get why you'd want bigger impact, but if its actively crippling character's combat abilities in exchange for choice of personality, personally think it's more than a little broken. Getting to choose personality might have few options at present, but now we've got even less unless we want to damage the character's combat skill. Sorry if sounds like over-pushing issue, just trying to explain thoughts.
Thanks for the tip about the effects file, will give go to try and get around issue. Probably going to end up removing the bonuses completely tbh, because not liking the system, but at least gives me that option.
Without taking a side in your ongoing discussion I'd like to say this though:
The developer has both the right and the responsibility to design as in 'make the entire game work'. You as a player refer to the past and insist on 'old' design while the developer has clearly changed the design. It has been clearly stated that there is still development ongoing which is why you should have kept the old version if you insist on a particular way of playing it.
You wish for a particular design to cater Your way of designing characters is a very personalized view whereas the developer has to cater for more than just one style. This game has excellent ways to modify things by yourself if one just invests a minimum of time and willingness to do so. This is the 21st century and editing simple code is not rocket science nowadays anymore. Make a mod. Really. That simple. Many coders started that way because they where not happy with how something worked. Dont make developers jump through hoops and risk the entire project being delayed or broken. Become part of the process instead.
Yeah, I can see that now trying to make a bold mage having a -25% MAttack, even with hidden powers boosting them, that's still -15% to their magic. In a way, I could make this work because, my thought process for her was she was a daughter of a noble house that think's she's very good, but in actuality, she's terrible at magic, the only problem for me outright is that now their is no immediate choice between them being a Slave or a Peon. Something minor that, I'm assuming can be fixed with a Writ of Exemption, but thinking on that, if everyone in the house only have slave status, that item will no longer be necessary.
