All tokens are gone

Hi,

I am using Comfy Cloud almost everyday. Yesterday, when I was making some tests with workflows, I was keeping an eye on my tokens. I had about 6900 tokens. Next day (today) I logged into my account and saw that I had 2 tokens left!

I looked up the usage history and found out that II had -0.02 dollars on my Cloud account. That didn't let me to work for today.
Also, today is my subscribtion renewal (19.03). About an hour later after checking my balance, I received th eemail with the bill - ComfyUI charged me with 35 dollars for the subscribtion renewal and I got my 7400 tokens for the upcoming month.

My question: why all tokens were gone a few hours before the subscribtion renewal?
Is subscribtion update is a reason or something else affected the tokens number?
How does it happened that more than 6900 tokens were gone at ones and I was cut out from the possibility to work for a day?

Please help me to figure it out.
