Many random issues. Double log in, can undo in store, and invisible champs not always working.

Ever since the problem with people logging in, i have to log in twice just to get past the log in screen. first time it always says riot is having an issue then the screen shuts off. however if i try again right after it works, this isn't a major issue but can be a pain. in random games sometimes it won't let me undo in the shop during the game yet other times it will let me. its been random and happening on aran and summoners rift. Final major bug I've noticed is during some games when a champ goes invisible i can still see them for a few moments as if i had a pink ward next to them when i don't. its even happened on Aram when Wu used his w under his own tower we all could see him still as if the tower was ours. even on summoners rift as shaco there would be no pink ward around yet for a few seconds after using my Q people could see me for a moments a chase me down. its become a problem and made it hard to pull off good combos as some champs. Idk if its happening to twitch or any other champs so far but as of now I've seen it happen to a few shaco's and Wu's.
