It’s a known issue that Faceit stats occasionally skip matches.
Here is a picture of the broken Main Statistics. It only displays 1 game played despite playing 3. https://gyazo.com/67fee4925c8d23d274ab98e5833a5a83
https://gyazo.com/4583194b3034d385641afe82fa157d3d shows my 3 matches. No update to my KDR, map stats, and more.
Statistics are a big part of CS and we expect that Faceit displays it accurately.
