Projectile Targeting + Multi Proj bug (Crossbow)

I have been experiencing targeting issues while using the crossbow. Projectiles will be aimed at the feet of monsters, this makes it nearly impossible to hit some monsters, such as the floating Abyss mobs that drop the desecrated ground, or small bugs that fly around (usually in a swarm). There is also times where I will have errant projectiles that just seem to fly in a random direction away from where I am aiming, and away from any other projectiles.

This also occurs when launching grenades, and it's when I'm noticing a multi-proj bug: Sometimes when I launch grenades with the multi-proj support gem, I do not get +2 projectiles.

I am getting +1 from my crossbow, and I will only get 2 grenades that launch.

Sometimes 1 of the grenades goes in a wonky direction as well (seems related to the targeting problem).

Most of the time the multi-proj issue does not occur. I don't know what makes it happen, only that it occasionally does.

The targeting issue is persistent all of the time and very annoying.

I was noticing this mostly when elevation is at play, like the bogs in act 3 and similar maps. If you target a mob that is at a different elevation or you target the ground of a different elevation by mistake you basically shoot yourself in the foot, literally.
Was this what you were experiencing?

Very similar yes, I didn't notice whether elevation was a problem or not, I was noticing it to be an issue in many places even in the Mines in act 2 where things are mostly on "one level" so to speak.

It is most noticeable using things like armour piercing rounds and fragmentation rounds. Fragmentation rounds seems like it happens less often, but when it does, it stops feeling like a piercing shotgun shot and like I'm just shooting it into the ground.
