I'm sure that I voted correctly, since I could receive NX normally before. However, these couple of days, I just couldn't get the 8000 NX. I tried voting for different accounts, tried to vote on my school's network, my home wifi, mobile data...I even asked for my brother to help me vote in another network, but the vote seem just couldn't register since the 24hr counter isn't on, and I could vote again and again without the 8000NX gain. Thanks in advance.
