Interesting, pay attention to this coin. my wallet is synchronizing for a long time
Yes this happened to me once too, I fixed by closing and reopening wallet a few times, each time it would increase the downloaded blocks. Since then it has worked fine. Also, you can update your nodes in your Deviant.conf file
