Vaal Blade Flurry instantly stops casting and has 0 range

Vaal blade flurry cancels the moment i cast it and it only hits enemies that are essentially on top of me. I think it could be a bug from when the game switched from units to metres to track distance/range, where the max range is still in units (0.9 metres now), would fit my observations.
Here's a vide demonstration:

On further testing (without hateforge which the video uses), it seems the actual bug is with it costing rage per tick. Earlier bug reports back this up as an issue as early as 2022
