Firefly Credits going missing without use!

Not sure why but I tried to generate some images yesterday, I wasn't able to due to too much traffic being online. I refreshed the same page a couple times throught the hour as to not lose the last images I had ( which also wasn't showing up in the generative history). I figured I would come back a different time, today, and upon refresh about 300+ credits are missing as if It took them when i refreshed the page. I generally keep track of how much is there after I finish generating for the day completely. I got 1000 renewed on the 17th, yesterday was 700+, today it was about 380 from doing nothing. From february to march I was generating constantly and couldn't finish th 1000 credits so it's no way I'm at 360 right now having only used it one day since renewal...
