Caliber you don't need to remove it, why are you so adament it works as it should when so many people are telling you it doesn't? Not to mention the problem, the cause AND the solution is all in this thread... it should be a simple fix for you. We are all following the instructions and doing it right.
"it should be a simple fix for you." <-- you say this as if you know the underlying code, and how difficult it is to reverse this stuff, divide it out, and make it do specific things. I have no idea what will happen 2 hours later when you do "X" with it either, or if it interferes with character "Y" that doesn't unlock until chapter "Z".
It's best I remove an option that is breaking the game or people are complaining about. You are asking for something I tried to do, but obviously it's causing issues. It's not as simple as "asking me for it" that I can accomplish anything and everything.
Sorry it has to go, but I have no other way of doing this. If it was 0, then you set it to 500, then you cannot upgrade, even if you reset it back to 0, then it's breaking more than just a simple value. If you can't use the trainer to revert back, then no need for the option, which appears to be the big problem for the game using the trainer.
best,
Cal
