Blue Essence glitch

I level up and got a level up capsule, I got draven and I disenchanted him because I didnt want him, it glitched and told me theres error, so I closed and opened my client and from 1600 BE I had 4000... the disenchanting gives me 900 tho. thats not everything, I also disenchanted other champion and got 6000 BE, enough money to buy irelia, I purchased her, played a game and then I had 6000 again. I mean, I am not mad, but I simply dont want to get banned for something like thi (so riot wouldnt think im cheatin or something)
