Concern About Significant Drop in Clay Credits Without Explanation

I logged into clay to create a new flow today after seeing some of the new features, and I noticed my credits were at like 8k even though they were at 80k at the end of the year, and I haven't really run any big queries since then, so would have only used about 1000 credits but somehow I'm down to just a few thousand left. I looked at the queries too, and no tables used all of those credits
