To all of you who are still wondering what is going on, you should really check into Discord... most things are explained there, and CC also logged in yesterday and explained the problem and his plan to solve it.

Currently there are a lot of branches in the chain, so if your wallet and the exchange are on different forks, then they won't be able to send transactions between each other. But chances are good that your funds are not lost, as long as the private key used for receiving is safe, as it will be valid in all branches, including the one that will be selected finally.
