Sudden change in LP gain and loss?

Hey guys, until yesterday I was getting 19-21 LP for a win and losing 17-19 LP for a loss but suddenly I am getting 15-16 LP for a win and losing 19-20 LP for a loss. This suddenly happened overnight. I actually won a game just now where enemy team's tier avg. was higher than my team (g3 vs g4) and I still got only 16 LP. Is this a bug or my MMR is just screwed? Is anybody else experiencing this?
