Navira's Oasis crashes Instances once used on Chilled Ground

I have been running multiple maps today where this was the case.
I used Cold converted Spark to procc Chilled Ground on Freeze with the "Frost Nexus Support" afterwards i follow up with casting Navira's Oasis from the new Sorceress Ascendancy "Disciple of Varashta"
I can tell that it must be this spell because it happened now multiple times and always with the screen freezing for a second and then instance crashing+Logout as soon as i pressed the Spell
The Character i played is called BladesFromAbove
I hope this can help
Thank you for your work!!
