Don't pick Zilean with Smite on Nexus Blitz

I have been enjoying my time on Nexus Blitz recently with Tahm Kench Jungle, and I wanted to try something a little out of my comfort zone, and went for a troll pick (Zilean Jungle). Eager to see how bad my jungle clears are, I wait a whole 8 minutes till everyone hits 100 percent on the loading screen, which is odd considering it's usually shorter, closer to about 2-3 minutes, maybe? Anyways, I wait at 100 percent for a good 3 or so minutes until I decide to alt tab and look at my status and the game was already started, without me in it. I've actually tried to do this twice now, and each time I tried I could not connect to my game no matter what I tried. I just feel like there isn't much i have control over regarding this situation.

Anyways, I'm probably going to get banned because I couldn't connect to two games, but hopefully if a Riot employee sees this and is willing to let these left games pass then I guess I won't try to do it until it's fixed, but I just thought I'd make it aware just in case.
