[0.4.21] non-displayed/incorrectly displayed dual wielding item stat penalty

[Prent]

When equipping a Sanctified Gladius in the main hand and a Flaming Dagger in the off hand, my 5 Willpower character should have a spell power of 29 (10 from Sanctified Gladius, 4 from the Flaming Dagger [lowered from 5 due to the dual wielding penalty], and 15 from Willpower). Instead, as the picture shows, I only have 28 spell power. I have no clue what's up with this

Post your save please. Its probably just a matter of rounding, but I can confirm with your save.

My bad, forgot to do that.

here, I uncorrupted myself and made another save with the gladius and dagger equipped.
