Dissonant Whispers might be causing Error: Firebase.update failed: First argument contains NaN in property 'current'

Not sure if I did anything wrong or if its known, but I found that using Dissonant Whispers breaks the API in my game. One of my players uses it a lot and it gets really annoying. I tracked it down after two hours of purposefully trying to break the API and this is what is causing it. Any suggestions?

The game is "Escape From the Depths" Sorry for the late response, I usually get a notification email, but did not this time. Thank you for your help!

They are clicking directly from the character sheet. Even tried deleting/adding the spell again. Under the attacks and abilities section. "Red" is the character breaking the game. "Sickening Radiance" is also breaking it.
