Didn't get LP after ranked win

Right before the ranked shutdown, I finished a long, hard fought ranked game in which we came back from a 7,000 gold deficit. Needless to say, it felt really good when I was able to get that hard earned 21 or so LP. However, after Ranked came back up, I noticed the LP had disappeared from my account. Anyone else have this problem and is it possible Riot could fix it?
