I was planning to do some casual matches and then go to sleep, but I entered a ranked match and saw this... What is this? I've never seen anything like it before..😅 It's quite baffling.. I thought it might be a bug, but it didn't seem like it, so I asked a friend just in case, and they said something similar happened before..😂 However, my friend didn't seem to know the details either..😢 Why are there suddenly 15 spectators in a room called 'Nonghyup'..? I initially thought it was a bug, but now I'm really wondering what's going on.. Does anyone know what this is? 🤔 Even if it's a simple bug, why 'Nonghyup' of all rooms..😅😅
