Weapon swap hydrosphere frenzy generation + other skills leads to disconnects

So i apparently stumbled upon a way to make people crash, the moment they join the instance.

My character uses hydroshpere + Frenzy to be able to generate frenzy charges before big bosses, Maven, Sirus that kind of stuff.

Skill wise i take use of Ice Crash with Fist of War support.

I tried a couple things to repeat this type of crash. Just using frenzy + hydro alone and the ice crash alone, nothing happened, no crashes or disconnects at all.

Edit: Forgot to mention that the hydrosphere + frenzy is in a bow in weapon swap.

Though the moment i would use both together, which i would generally do within a big fight, if i was trying to help others out with their bosses. That means generating frenzy charges on the sphere and killing the boss with ice crash, it would lead to others joining the instance, to straight up just disconnect and get send to the login screen.

The way i found i could easily replicate it.

1. Weapon swap to a bow with frenzy and hydosphere socketed
2. Frenzy generation combo with hydrosphere
3. Switch back and use use the attack skill

I also did make sure to try another skill, specifcally a slam skill, Earthquake. Exactly the same thing happened, so this is not tied to Ice Crash, but more so Hydrosphere + Frenzy or possibly any other bow skill

This kinda breaks the character a little, as it was nice to have the charges ready for when the boss got active.

Have you tried restarting your PC as well as deleting temp files?

Not sure how that would help. As this is an issue that makes others joining disconnect.

I can leave the instance and join again, due to having already played through the animations and effects. I do believe it is tied to effects
