Two years later i get hit by the same bug Vaal BF not working with Fueled by hate/Hateforge

Years ago when hateforge was implemented i tried to use Vaal Blade Flurry and it wasnt working i reported it and moved on, never had the opportunity to try it again since i play ssf and never got the gloves again.

This time around i went Behemoth Fueled by hate with the sole purpose to finally try it and somehow its still broken and not working.

It sucks all your rage for one frame and then it does stop working, it literally just burn all your rage and does nothing, channeling vaal skills should only pay the initial cost ffs...
