New hack or just a weird glitch?

I'm honestly not quite sure which one it is, but I'll do my best to explain it:

So I was just queuing for a normal draft game, our 2nd pick goes eve and picks continue as normal, seeing as I'm last pick and we have eve I grab urgot since I'll probably be alone at bot lane most of the time, here's where things get weird though. The moment picks end and the count down starts, eve switches champs with me, no trade prompt or anything and everyone else on the team randomly starts trading champions. At this point I'm really confused and try to trade the guy who picked eve to get urgot back, get him and instantly get given back eve. I really don't know what would have happened if the game started since I dodged last second not wanting to get into a game as eve.

Anyone else been having problems like this? The fact it was the Eve player that started it makes me think it might have been malicious.
