Spring Patch Event?

I've read this morning just after the server update that there was an event this weekend:

Thursday: Play in 10 HM/MM games and get a 7-day mutation magazin
Friday-Sunday: 10%+ GP

Now i can't find this back anymore. I think i've read it in the launcher window but it's not there anymore. Also can't find something on the website or forums. Can some mod clarify this? ><
