Glitch TFT

In my most recent match of TFT i came across a glitch. This glitch allowed me at the random champ pick to put an extra person on the map. What had happened is that i had a full inven of champions and max amount of champions on the map, once the last pvp happened and all players were sent to the center for a champion pick i chose draven, once all players were teleported back to their area draven had appeared on my map. at first i thought it was a place holder until i realized next match that he was actually attacking and doing damage to the enemy team. my current level was 6 and with draven now on the map i had 7 total champions. Now this did however prevent me from changing in and out of other characters i believe this can have some negative impact and people can use this is worse ways to gain an advantage over the enemy early. just figured i would make a post about it. IF THIS IS NOT A GLITCH AND SOMEONE CAN POINT OUT WHAT IT IS PLEASE LET ME KNOW!

NOTE: no. i didnt combine 2 of spatulas to gain that perk to add a champion above my max lvl.[zombie-brand-facepalm]
