Ability Checks error??

[Captcorajus]

I was playing around with the rules set, and it seems every time I roll an ability check, the modifier is 1 off. That is, if I have a score of 13, and it says +1, and I roll the die, it gives it a +2. Am I doing something wrong?

Hey Captcorajus! In C&C your level is added to all Seige Checks.
