Nightfall Flame Dash black box bug

As stated in the title. There is an annoying bug with the nightfall flame dash MTX. every time you use it, a black box appears and covers the whole character for a few seconds then disappears. It only occurs upon the use of flame dash. This means that I cannot use the MTX that I paid for which is unfortunate. I hope that you will fix this soon.

I'm just now getting this after a week of having it. At first i figured it was a poe overlay issue but even when moving flame dash to another key it was still doing it. This is new, needs to be fixed now.

Also Just started getting this bug after having the mtx working fine for the last week.

I've just started having this issue.

It happens when I combine it with emperor's vigilance shield, I did a skin transfer of that shield onto my shield, and the black box occurs.

It doesnt happen on regular flame dash, and it doesnt happen whit my previous shield, only when its equipped with emperor's vigilance

theres a few other mtx's on my character but i've played a good 2 weeks using them, they've never done this

It's fairly large aswell, big enough to cover over the force field aura mtx

Can confirm it seems to be occuring with Emperor,s Vigiliance shield (either the shield itself, or skin transfer).

Using nightfall flame dash causes a big black box, doesnt do it with any other shield or with any other flame dash effect

This is still happening. Can we get a fix please? Its been 3+ months now.
