Avian's Might resetting weapon effects and 'quicksand' effect

I suppose I'll add images first to make it clear what's going on here.

Avian's flight:

Avian's might:

Avian's flight is showing my character as it is supposed to here: with the sand color from the quicksand buff. Whenever avian's might turns on however, my character gains its normal look again even when the debuff is still applied. This change happens everytime Might and Flight swap over.

As for a clearer picture of the weapon effect not applying correctly, I've made a clearer side by side:



The image is cropped a bit to save space, but it is showing Avian's Flight on the left, and Avian's Might on the left.

Note that the particle effects on the weapon still get applied under Avian's Might, it's just the color of the bow that doesn't get applied. I've noticed the same behavior with the Sin, Legacy, Prophecy, Ultimate Chaos, Harpy, Ghostflame and Perandus effects.

PS: I used the arc of courage skin for added clarity of the bow, it also happens when no mtx skin is applied.
