Bugs I've Found So Far
So far, after playing a handful of games, I have found a few bugs. -Twitch, when healing in stealth, becomes instantly visible. Being an avid Twitch player, I had never noticed this being a game mechanic last season. I'm pretty sure this is a bug. -Statikk Shiv's detection radius for its passive is bugged. Sometimes it will arc to nearby enemies/minions, sometimes it will only hit that single minion and ignore all other surrounding units. -Tiamat/Hydra's passive only works half the time. I play a game as Kha'Zix and noticed the passive splash was not working. I spoke to a friend about it who also said they have had a similar issue in multiple games.
Feel free to add on to the list, as I will with all of the bugs I find. I'm sure there are some that I left out, but I will add them in if I remember them.
