Bug Report: Improper Ability check calculation

Level 1
1 year ago (edited)

When examining the craft DC of a manacalon rosary item(Whiteburn, in this case), the Ability check is incorrectly showing as INT d20-2147483648.  This looks like an integer underflow/overflow issue, and is occurring when checking the DC with someone who is not proficient in Manacalon Rosary.  Additionally, when viewing the DC with someone who has proficency, the Ability Check calculation reads INT (Manacalon Rosary) ..., and does not give the bonus.
Neither issue is serious, and a supporting image is shown below. Or the forum ate it instead.
