We don’t really know, it’s speculation. Riot has been doing night markets for a while now. I’m wondering how they messed up this badly by giving players free skins and giving discounts on already owned skins. This means someone/group in the developing team messed up by accident, tampered with the code, or reworking the night market (one theory I have, also btw I have no knowledge of game development, but what if they were testing a new night market and some coding was implemented in the old night market by mistake)
New night market may be adding more offers, changing rules of what’s allowed, or something else
