Rend (wyvern melee) sometimes glitches with weapon swaps

I have been using primal and swapping with other weapons. I noticed an occasional glitch where rend, the wyvern base attack, will basically stop working on not connect with mobs.

Even after attacking and killing mobs with other abilities, the rend ability is still glitched.

Resetting or changing my weapons from slot 1 to 2 and 2 to 1 seems to fix it but it can recur.

Just a little bug that is annoying. It's frustrating to die due to a bug or not know why something isn't working.

*edit:

this may be in part from having a support that only allows damage to low life targets, like the headhunter support from the vaal temple.

but im finding this happening to abilities that dont have this support in them as well. just frustrating as it is making a weapon swap build with primal very frustrating.

Just adding that this occurs with other wyvern attacks too. I experienced this with the oil breath attack -- it just wasn't registering as hitting anything.

It might be a conflict with whirling assault because I have been using that with primal abilities, but it doesn't always glitch up so I don't know the exact cause.

Just adding here. This happens with a variety of other weapon types. Not just quarterstaffs or whirling assault.

Unequipping and re equipping weapons is the easiest way to reset it.
