bugs in aram (hp bar, lock screen button disappeared); Ahri having similar bug as ASol used to be?

Just reposting this from the one I had at Help&Support (didn't see we have a Report A Bug place before I post and that's where I usually go - I apologize)

played a few arams today and during my last match as Teemo - my lock screen button (at the bottom right corner right by the mini map) disappeared (and I am a lock-screen user - no judge pleaserino). Then after I found the hotkey (which is Y) for lock screen - my HP bar actually disappeared. By that I mean the color looks like as if I am a dead Teemo all the time (is this a Halloween prank?) while I am actually alive.

In the game before this Teemo one - I actually see Ahri's W (Fox-Fire) staying at the same place while Ahri herself is no longer at the position.
