Encountered 2 bugs/glitches in ARAM today.

Today was a pretty normal league day for me until i played some ARAM games... The first bug I encountered, was that the ultimate from Kennen was invisible. I know that Riot is already working on fixing this, but I don't want to leave this bug unignored. The second bug was that I kept teleporting back over and over again. This happened when i ran out of spawn and just as i passed the left nexus tower I teleported back behind the nexus. My reason for reporting is, that maybe these 2 bugs are ARAM related, 'cause I haven't seen these 2 bugs on Summoners Rift. (I am sorry that I don't have any pictures or videos of the problems.)
