This might seem a little pedantic, but the colours displayed when both bonuses and negative effects are applied at the same time is incorrect.
I've currently got a +5% attack bonus from an Ancient Crystal Foci. However, i've also got a -25% attack Dark Nullify effect from attacking the Dark Ring. Overall, this should mean I have a -20% attack "bonus" (Assuming it's additive).
However, my weapons are showing up in green, not red, so it looks like whatever code tells the game what colour to display, isn't managing the colours correctly when different effects are applied.
I'm also noticing that sometimes, when I hover over bonuses, the bonus is duplicated in the display.
Sorry if these issues have been mentioned before, but i've not noticed them on the forums.
