Ok, I've never made a post here, but in this patch I'm experiences several different bugs - over and over again. Also, I couldn't make a post with my main acc on EUW for some reason... anyway:
1) Malzahar Ulti. The Ulti is shown that it's on cool down for malzahar while my team can see the green dot indicating that the ultimate is active. I've had it twice so far.
2) Minimap: Champions appear randomly on the minimap. It's ridiculous. You see Vi somewhere at her own blue. You engage and suddenly Vi is next to you. Happened ~10 times so far.
3) Minor Syndra Lighting Bug: Dunno, the balls flying around her glitched a bit...
But especially #2 is a real big issue to me.
