Scion's Q and R broke mid match (very early on)

I played a simple bot match with scion to test out his changes as i do with most champs just so i can get a feel for him before i use him in a regular match. But probably around 10 mins in i ported back to fountain and suddenly his Q and R simply will not work. Neither hotkey nor directly clicking on the abilities have any effect which basically render him near useless. Any reason this happened or is it happening to others? (p.s. if the other tiny details matter i was 3-0, maybe ~30 minion kills, my first time porting back to fountain, and i bought tiamat+longsword, rank 2 or 3 Q and R1 R, everything after that that i did did nothing to fix them)
