Camille + Vi Ult... bug

Not sure what the process is here or if this issue has been brought up but here are the details...

• Live ranked solo Q game on NA server(Jan16/2017 around 10:20pm EST)
• Camille(me) ults enemy Vi
• Vi ults Rengar(outside of Camille ult zone)
• Vi becomes untargettable and gets stuck in a repetitive motion, ramming into the edge of the Camille ult zone
• After Camille ult zone comes down, Vi completes her ult on Rengar who is triple the distance away of her regular ult range

I do not have video footage but if there is anything i can do to help, please let me know.

Cheers
