I lost lp in champ select, my internet was fine, i was streaming, i pressed lock in, but my champ didin't lock in.

The stream time on my computer should show it happening at 1:59 AM so skip to then. I would like to get my lp back since i just needed 1 more win to get into promos, 81 lp dropped to 78 for lp deduction for dodging. i don't want to win a game and get 99 lp. I know i will. If not this is a bug that riot should fix, because this kinda made me mad
