There're still a few wallets connected to the wrong chain. The explorer is on the wrong damaged chain (Yobit exchange probably). If you stake, check the network weight to ensure you're on the correct one. Also, when you're sending Crave to Unnamed exchange or out of it, make a test transaction first to ensure, the exchange is on the correct chain. The subscription of the cryptoid explorer ends in 18 days and the official Crave web site crave.cc doesn't work at all.
