All BAT disappeared for the first time

I had over 30 bat and format my PC after saving the wallet phrases. I became very busy over the next few months, couldn’t get around to reinstalling until now. I just restored my wallet and it’s 0. I had turned off all automatic contributions before so I can’t say where the BAT went. I figured maybe it just needs a minute to update the wallet data or something but it’s not adding them back to my wallet. It’s just adding new BAT to estimated earnings. This is the first time I’ve experienced this.
