AATROX - UNABLE TO USE SUMONER SPELLS

Playing as Aatrox top vs Rengar, when i got killed by a gank (ZAC), after respawn both my summoner spell´s went dark (like an unlearn ability) and couldnt use them at all, even after i tried to reconnect. THE FIX CAME after Aatrox passive went up again and then got killled, AFTER THE PASSIVE TRIGGERED AND I REVIVED THE SUMMONERS BECAME USABLE AGAIN, for the rest of the match, although it was very annoying since i played without my summoners for about 10 minutes and got completely crushed. Pls fix
