Stats either resetting or dropping randomly?

I thought this has been happening several times over the past few weeks, but I've verified today that it's actually happening where my stats are either dropping or resetting to a certain point.

For example, I had over 900k agility prior to going to work today. I come home, and I'm under 900k agility. No changes in gear, nothing. I didn't even refresh stamina while at work, so this shouldn't be happening so far as I know.
