Massive points lost?

I had approx. 4800 S3 points last night when I went to bed. When I logged in this morning to claim my daily reward, I had about 4400. I’m not saying it’s impossible that I lost enough matches to lose 400 points, just that I’ve never seen that many be lost in a span of about 8 hours. Anyone else lose significant ground recently?

When you logged in, did a little screen saying “you’ve been hit” pop up with 400 points worth of retaliation opponents?

Nope.
