Brothers, pay attention, don't open the B/usdt contract yet. I encountered a terrifying bug where after opening an order, that order suddenly became untraceable and disappeared from my positions. I couldn't operate it; it completely vanished and only reappeared after a while. It has disappeared and reappeared several times now. This is just ridiculous; this is a contract, how can there be such a malicious bug? I am waiting for customer service to reply to me. I was originally going to bottom out and make a super short-term play on B, and it scared me.
