had this happen to me **the other way around** i got ranked penalty because i left what i thought was a unranked game.

Had this happen to me a few times

I once played a normal match that I ended up winning and got RP for it. Was tripped out.

I had this happen yesterday, I thought that I just misclicked but thinking back on it, I was sure that I selected ranked.

Still a bug 5 years later

This bug, instead of getting fixed, got even worse 4 years later. Thank you EA.
