There are some instability issues currently ongoing on the our blockchain. These cause some core clients/wallets losing peers and possibly forking.
As a result, most exchanges have suspended PIVX transactions.
The developers have been at work to solve the problem and already have a new release, v4.1.1, of the core client.
This is not a binary yet, so you will have to compile it yourself.
Final binaries for the usual operative systems will be available soon.
Meanwhile, you can check if your core client has actually forked here
