I have 2 rp codes pending, over max date and I still haven't obtained it. I also have 2 RP codes pending. One for yesterday and one for today, timed so that’s I could get all the Valentine’s Day stuff before it was gone. Being as you’ve waited a week, and the Valentine’s Day stuff isn’t only here for two weeks, I’m starting to sincerely doubt Sweetheart Xayah or her Emotes will be anywhere in my future.
