Actually I did. I was trying to figure out what people were doing (I got a late start playing the game) and it was time to take the dog to the park (5PM He knows and reminds me). It wasn't until after I googled it when I got home that I found out about all the free engrams. Too bad that was the week it got patched and I never did get a single legendary engram from it. Although I have gotten a few there waiting for the Public Event to spawn.
